    Brake pads are a part of the braking system. In many ways they determine how quickly the vehicle will stop. When the pedal is pressed, the shoe is pressed against the disc, which leads to the vehicle braking.

    Types of brake pads

    • Semi-metallic. Pads are made of iron, copper and graphite powders. Their advantage is a good heat transfer and disadvantages are rapid wear, loss of properties when the temperature drops and the presence of noise when braking.
    • Low-metallic. This is one of the best types of these components. Their composition is the same as that of the organic and improvement of properties is obtained by adding copper or steel, that allows a better heat removal. The only drawback is rapid wear of the brake disc.
    • Ceramic. Virtually no drawbacks: the ingress of water does not affect the performance, brake discs wear is minimal, and the dust and the heat are released to a much lesser extent than in the above-described analogues.

    The construction of brake pads

    The basis of the part is a metal plate with fixed friction lining on it. Pads repeat the form of a brake disc or drum. A pad is attached to the base by means of rivets and special adhesive. Many pads have wear sensor.

    Tips for operating the brake pads

    The service life of the brake pads depends on driving style and mileage. Sudden acceleration and deceleration wear the part out faster. On the average, its lifespan is 15 000–20 000 km. It is not recommended to exploit pads if lining thickness is reduced to 2-3 mm, since there is a risk of damage to the brake disc and the brake fluid boiling.

    Malfunctions of brake pads

    • part is deformed;
    • the appearance of free play;
    • damage or break of the friction surface;
    • heavy wear of pads.

    Symptoms of brake pads failure

    • uneven wear of parts;
    • wear indicator reading;
    • appearance of rattle or squeak in the wheel during braking;
    • increase in force when pressing the brake pedal;
    • the pedal does not return to its original position after release;
    • degradation of braking effectiveness.

    Causes of brake pads malfunctions

    • item is not properly secured;
    • wear of the brake disc;
    • dust, dirt and foreign objects in the lining;
    • improper installation;
    • aggressive driving;
    • a fault in the brake cylinders.

    Repair and replacement of brake pads

    Repairing and restoring the pads is not recommended. In case of malfunction they should be replaced, especially because their cost is relatively low. Replacement parts will extend the life of the brake disc and the entire brake system. You can replace a pad by yourself with a minimal set of tools. To do this, follow these steps:

    • lock the car using the handbrake and raise it;
    • remove the wheel;
    • knock out retaining pins and guide pins;
    • using pliers or a screwdriver, drown pistons in the cylinder of a caliper and remove the old parts;
    • lubricate guide pins with oil and perform the above steps in reverse order.


    Brake System auto parts: Wheel speed sensor Master-Sport Automobiltechnik (MS) GmbH 

    Many cars have ABS (antilock braking system) that prevents locking of wheels when braking. Due to this system even when full braking on the slippery road, the car remains controllable. ABS system is especially useful on wet roads. Problems can occur when braking on a soft or loose ground, because in such cases ABS reduces braking efficiency. Therefore there is possibility to disable ABS. A special ABS sensor is required for ABS system operating. It records the rotation of wheels. These data are necessary for the timely prevention of wheel lock.

    ABS sensor is a wheel speed sensor that works with high accuracy. In older vehicles primarily are used passive inductive sensors. Modern cars are equipped with active sensors. In many cars on the wheel hub is mounted a simple gear ring. The sensor is placed above its end face. ABS sensor is usually mounted on the rear axle. When buying, make sure that you have chosen the right model. In the course of time a lot of manufacturers have many times improved their ABS.

    For a layman it is quite difficult to determine whether the ABS sensor is defective. The reason that ABS is not working properly can be any other component. Workers of service station will quickly determine whether it is necessary to install a new sensor ABS. It is not difficult to install the sensor’s toothed disk. In our online shop you will find many car parts of the highest quality, such as starter, brake disks, electric window lifters, fenders, bearings and shock absorbers. It is very easy to order goods in the Internet and it is the cheapest variant. Therefore, you should visit our online shop.

    Malfunctions of ABS (ESP) sensors

    • sensors work incorrectly;
    • contacts are closed or oxidized;
    • sensors were damaged as a result of mechanical impact;
    • wiring is broken.

    Signs of ABS (ESP) sensors malfunctions

    • wheels slip when the car is started sharply, or the car is skidding at emergency braking;
    • ABS and ESP lights illuminate on dashboard;
    • increased fuel consumption;
    • engine has lost power;
    • increased braking path on slippery roads.

    Causes of ABS (ESP) sensors malfunctions

    • components are connected incorrectly;
    • microcircuit of sensors got damaged;
    • faulty fuses;
    • car regularly starts harshly;
    • braking system is broken;
    • car did emergency braking at high speed.


    To check, if ABS (ESP) sensors work correctly, an oscilloscope and a multimeter are required. Resistance between sensors contacts must be within 1-1,5 kOm. If the reading exceeds admissible values, you are required to check fuses and wiring. Software is also requires thorough diagnostics, because electronic malfunctions can cause mechanical faults.

    For checking you can replace sensors with ones which are 100% correct. If the tested sensors work with faults, than you should also check systems connected with the sensors. If non-original components are used, than insufficient contacts connection can cause malfunctions.

    While doing output test, check proper functionality of braking mechanisms. To define if TCS (traction control system) and ABS (anti-lock braking system) systems work efficiently, you will need a specialized bench.

    Repair and replacement of ABS (ESP) sensors

    Before repairing, you should find out the source of damages. For this, complete examination is needed. In case if microcircuits of components are damaged, they can be restored. Though, such services are seldom offered even at big service stations.

    If a vehicle is suddenly stopped at a speed higher than 100 km/h, than sensors settings can fail because of heavy overload. In such cases, the parts should be adjusted and checked. It is recommended to replace damaged parts exclusively at service stations.


    Brake System auto parts: Brake shoe set Master-Sport Automobiltechnik (MS) GmbH 

    Brake shoes refer to the drum brake. Wheels brake in the drum brake, meanwhile brake shoes press the rotating cylinder. Due to the mechanical friction, braking effect is achieved. In cars the parking brake can be the drum brake. It is independent of the operating brake and serves mainly to provide car standing. If the hand brake is on, brake shoes prevent vehicle rolling. Due to this it is possible to stop the car on the inclined surface.

    Sooner or later brake shoes wear out. Still, they are not highly subject to tension and serve for a long time. If the parking brake is not effective, the reason is worn-out brake shoes. Braking can be precisely measured on the brake test rig. It is easy to replace the shoes on the platform lift. Moreover, often it is necessary to dismantle wheel bearings. So, it is better to entrust this work to the repair shop. Brake shoes should be replaced endwise. Usually, it is sufficient to install the parking brake on rear axle only.

    Also it is possible to repair brake shoes in rear car. Sometimes it is rather difficult to find an appropriate car part for rear cars, as they are very expensive. In popular car models it is better to install a new car part. Do you need to repair something else? Then we can help you to find cheap, but quality car parts. In our online shop you will find interior blower, catalytic converter, boot lid, condenser, dumper strut, window lifter and other car parts you need.

    How to identify a faulty drum brake shoes kit

    To diagnose drum brake shoes, lift the vehicle with a jack and remove the wheel. Then lower the parking brake lever, and remove the brake drum. The degree of shoes wear is determined by the thickness of the brake linings. Measure it without taking into account the metal base, using a vernier caliper or a ruler. The lowest allowable value is approximately 1.5 mm. The exact figure is available from the manufacturer's manual.

    If you do not have experience or necessary tools for dismantling drum brakes, contact a service station to have the components diagnosed. Brake shoes should be diagnosed after every 20,000 to 30,000 km of mileage.

    You may notice that the drum brake shoes kit requires diagnostics by the following criteria:

    • screeching, rasping and whistling sound while driving;
    • wobbling in the area of the wheels during braking;
    • increased consumption of brake fluid;
    • increased braking distance.

    The reasons of malfunction of a drum brake shoes kit

    In the process of operation, drum brake shoes are subjected to heavy loads. The reason of the premature wear is oiling of the linings.

    The service life of the components varies between 100,000 and 150,000 km, and partly depends on the driving style and driving conditions. Aggressive driving, abrupt and frequent braking on wet roads, and poor road surface reduce the service life of the components.

    An important factor is also the quality of the material the components are made of. Poor quality shoes wear and get damaged much faster.

    Replacing a drum brake shoes kit

    Brake shoes are consumable elements of the mechanism, so they are not subject to repair and restoration. The components are to be replaced simultaneously on the same axle. The algorithm is as follows:

    1. Lift the vehicle using a jack.
    2. Lock the front wheels of the vehicle with bricks or other chocks.
    3. Disengage the parking brake.
    4. Unscrew wheel nuts and remove the wheel.
    5. Unscrew fastening of the brake drum and remove it.
    6. Loosen the parking brake cable.
    7. Remove hold-down springs.
    8. Remove brake shoes.
    9. Install new components in reverse order.

    If, while replacing the brake shoes, you find any deformation or wear of the brake drums, the latter should also be replaced.


    Learn more about Brake discs Master-Sport Automobiltechnik (MS) GmbH - operation method, diagnosis, causes of faults and replacement intervals.

    Brake disc is a component of the braking system, which is responsible for slowing and stopping a vehicle. Due to continuous thermal influence brake disc is made of durable material.

    Types of brake discs

    By type of material used:

    • Cast iron.
    • Carbon.
    • Ceramic.

    By the presence of ventilation:

    • Ventilated. They consist of two plates with a gap between.
    • Unventilated. They are a solid plate with perforations, incisions, or without them.

    By type of perforation:

    • With through holes. A highly effective cooling, diverting exhaust gas and combustion products. However, they have little durability.
    • With the deep holes. Have a long period of operation.

    Tips for operation of the brake disc

    The service life of the brake disc depends on the material from which they are made, and driving patterns. Often, it is necessary to replace brake discs every second pad replacement, that is 30-40 thousand kilometers. Exact recommendation for disc replacement frequency is specified in the technical specifications of the vehicle.

    Malfunctions of the brake disc

    • scuffing on the surface;
    • deformation and abrasion of the brake disc;
    • uneven thickness ratio of the part circumference;
    • the appearance of cracks on the disk;
    • the destruction of parts.

    Symptoms of the brake disc failure

    • when braking, the vehicle deviates from a predetermined path of movement;
    • when braking, whistling or grinding comes;
    • the brake pedal vibrates when you press it;
    • significant increase in the braking distance.

    Causes of the brake disc malfunctions

    • excessive wear of parts;
    • prolonged exposure to moisture;
    • installation of shoes with low-quality pads;
    • damage of mechanical origin;
    • systematic hard braking.

    Repair of brake discs

    At the first sign of failure, measure the thickness of the disc with a caliper. The deviation from the original values ​​can be of 1-3 mm.

    Extended life of the brake disc can be achieved by grinding. Special equipment removes the small cracks and burrs, levels the entire circumference of the thickness of parts. It must be remembered that this is a temporary measure, you still have to replace the discs.

    Replacement of brake discs

    Installing new parts is easy. This can be done by yourself. To replace the disc, you need:

    1. Lift the car with the help of a hydraulic lift or a jack. Remove the bolt and remove the wheel.
    2. Remove the caliper by unscrewing the screws located on the back side of the part.
    3. If there is such a need remove the caliper mounting.
    4. Remove the disc by unscrewing the fixing to the hub.
    5. Install a new brake disc.
    6. Secure the caliper mounting, establish the caliper, wheel, lower down the car.


    Brake System auto parts: Brake Drum Master-Sport Automobiltechnik (MS) GmbH 

    Brake drum is a part of brake system that plays an important role in braking. Braking effect is achieved by converting kinetic energy into heat that is absorbed by the brake drum. This is a simple mechanical process. But there are special material strength requirements, which the brake drum is made of, as it is subjected to strong mechanical stresses. In brake drum friction pads are located inside the drum, while in the brake shoes or clamping bands friction surfaces are outside.

    Excessive heating that occurs during braking, requires the use of special alloys with a high wear resistance. However, wear occurs. So each time you change tyres, inspect the brake drum for obvious signs of wear. It can be deformed, for example. If you find defects or signs of corrosion on the surface of the drum, screening is necessary. Manufacturers specify the maximum diameter of the brake drum. These values should be guided when estimating wear. In addition, brake drum can be damaged in the result of an accident.

    Worn brake drum or drum with a clear defect should be replaced immediately, because the risk of brake failure is too great. Brake drum replacement should be done in the auto repair shop. Brake system repair is related to car safety and even the slightest error can have serious consequences. So do not do this by yourself and trust professionals. In our online shop you will find rear view mirrors, mufflers, spoilers and fenders. You will be able to install them without any assistance if you have mechanical skills. Our Internet shop guarantees the best quality and reasonable prices.

    Brake Drum failure

    • part surface deformation;
    • increase of the gap between shoes and drums;
    • drum entire surface worn-up;
    • part deformation;
    • wear out;
    • oiling of the part working surface;
    • cracks or indents occurrence.

    Signs of brake drum failure

    • worsening of vehicle response;
    • lengthening of brake path;
    • vibration or extraneous sounds when braking;
    • beating vibration of the steering wheel or brake pedal;
    • skids when braking;
    • excessive free travel of the brake pedal.

    Causes of brake drum failure

    • untimely components replacement;
    • sporting driving style;
    • damages or worn-out drum return spring;
    • usage of low-quality consumables;
    • frequent driving on the roads with low-quality surface;
    • installation of unsuitable parts or faulty components;
    • thermal impact.


    The experts will perform diagnostics of the entire braking system at the service station. It is examined at the special repair bench where the resistance of each of the wheels when braking will be estimated. We remind that the maximum indicator of the drum diameter shouldn’t exceed 204,4 mm. Higher rate testifies that the component should be replaced. We will note that you will be able to diagnose the system yourself. So, accelerate the car to 70 kilometers per hour, be sure the road surface is flat and dry. Then press the brake pedal sharply. If the car starts skidding or if you feel the pedal or steering wheel vibrations, hear extraneous sounds, you need to inspect the braking system at the service station urgently. Inspect the system in such way every 20000 operational kilometers, and do the cleaning and preventive maintenance of the unit every 10000 operational kilometers.

    Brake Drum repair

    Perform the machining of the drum in order to remove surface shears that increase braking path and make the car vibrating. Also it should be taken into account that repair work will be much cheaper than brake drums replacement. The serviceman removes the top layer by the lathe thus restoring initial condition of the part.

    Brake drum replacement

    If you found brake drum failures that you cannot eliminate, replace the component. It will be reasonable to replace the part at service station where high-precision calibration of the braking system can also be performed.

Brake system car parts Master-Sport Automobiltechnik (MS) GmbH - all important information about operating method, mounting, diagnostics and service life

A braking system comprises several components designed to ensure a controlled stop of a vehicle at a particular moment. It is also used to prevent the car from rolling when the driver needs to park it on a slope.

Brake system design

There are several types of brake systems. Nowadays, the most widespread layout is a hydraulic system with disc brakes. Its key elements are the following:

  • Pedal – by depressing this, the driver operates the system.
  • Brake booster – this multiplies by several times the force applied to the pedal to make the system work efficiently.
  • Master brake cylinder – this creates the pressure required for the operation of many actuating mechanisms.
  • Hoses and pipes – these ensure that the working fluid is supplied to the cylinders.
  • Pistons – the fluid pressure forces these out of the cylinders, and they press the brake pads against the discs.
  • Caliper – this is used as a housing for pistons and pads. In floating components, the calliper bracket presses one of the pads to the disc.
  • Pads – these are elements of the friction pairs and have a friction surface. When the driver depresses the pedal, they are pressed against the brake disc. The friction force created between them stops the wheel rotation.
  • Discs – this is the second element of the friction pair. It is mounted onto a wheel hub and rotates together with it.

In drum brakes, brake shoes together with the wheel brake cylinder are installed inside the drum. When the pedal is engaged, the brake fluid pressure pushes out the pistons of the wheel cylinder. They overcome the resistance created by return springs and press the brake shoes against the internal surface of the drum.

Parking brake systems are fitted with a cable instead of a hydraulic actuator.

Maintenance advice

  1. Replace the fluid once every 2–3 years. It absorbs moisture through the pores in rubber hoses. With time, the concentration of water in the braking fluid rises and its boiling point reduces significantly. If the fluid boils, air locks appear in the system, which decreases its efficiency dramatically.
  2. Replace the hoses every 5 years. The rubber and other polymers they are made of are subjected to wear and tear. Over time, they lose elasticity. As a result, the high pressure created in the system is neutralised by the excessive width of the hoses. The remaining pressure is insufficient to move the pads or shoes and press them against the disc or drum.
  3. Measure the thickness of discs and pads regularly and replace them if needed. A worn-out disc may even crack. Due to wear and tear of the friction lining, it becomes impossible to achieve the required level of friction.
  4. Lubricate calliper guide pins and replace the sealing elements every now and then. This way, you’ll prevent jamming of the assembly and uneven wear of the pads.
  5. Use anti-squeal shims. They will help to avoid squeal and make braking more comfortable.

Symptoms of malfunction

When the brake fluid level warning light comes on, this usually means that some brake system components are leaking. In that case, you may notice yellow, amber, pink, grey, blue, or purple puddles under the vehicle after it’s been parked for a while, usually around the wheels. The car may pull to one side, which is often a sign of a jammed calliper. Similar symptoms appear when oil gets onto the pads, while increased pedal travel or low pedal resistance usually indicate that there’s air in the system.

Causes of malfunction

Most often, these problems appear when the driver neglects to replace brake system components on time. For example, a jammed calliper may cause uneven pad wear and deterioration of the brake disc. Old seals and hoses lose their elasticity and crack, causing the system to start leaking. Worn-out guide pin boots often lead to dirt and moisture getting on contacting parts, resulting in corrosion and jamming. Aggressive driving may lead to disc deformation.
