Car braking system- this is the most important component of your driving safety. Hundreds of thousands of accidents worldwide occur due to brake failure. To protect yourself and those around you, you should regularly monitor the technical condition of your car's braking system and maintain it in accordance with the manufacturer's recommendations.
The braking system of almost all cars consists of the following components:
- Brake pipelines. A special liquid is used in hydraulic pressure transmission systems from the pedal to the brake. It is stored in the master cylinder and enters the calipers through the brake lines.
- Brake pads- are pressed against the disc and create the friction necessary to slow down and stop the car. They can be made of metal, ceramic or organic material and be vented or non-vented.
- Brake discs- have the shape of a circle and are attached to the wheel, receiving kinetic energy and turning it into thermal energy, which is then absorbed and dissipated.
- Support- press the brake pads to the discs to slow down and stop the car.
When to change brakes?
If you do not know the exact mileage of your vehicle,general ruleis to inspect the brake system annually or every 30,000 - 50,000 km. Pad replacement terms are 15,000 - 30,000 km, and discs should be changed every 80,000 - 120,000 km.
The numbers may vary depending on how you drive. If you're hauling heavy loads or spending a lot of time in traffic, your brakes will wear out much faster than a car used for highway driving. In addition, if you are an active driver, brake often and hard, the components will wear out much faster.
How to determine the wear of brake discs?
As a driver, the first thing you may feel while driving is that something is wrong with your brakes. If you notice one of thethese signs, then most likely your brake discs are badly worn:
- when pressing the brake pedal there are strong vibrations;
- regular beating of the pedal during braking;
- a metallic screech that can change pitch as the wheels spin.
These are subtle but clear signs that the brake system should be diagnosed and worn components replaced as soon as possible.
If you have the opportunity to remove the wheel, dismantle the pads, the caliper and inspect the entire surface of the brake disc, you can determine the problem without a trip to the service. To find out the degree of wear of the brake disc, there are severalmethods:
Check the control labels- manufacturers, as a rule, apply special grooves, according to the condition of which the degree of disc wear can be determined. If the mark has completely disappeared in the contact area of the disc with the pad, it is worth replacing the part with a new one.
Measure the thickness of the disc. This can be done using a caliper. But what should be the thickness of the brake disc? In most cases, you can find the minimum permissible values for the brake disc rim thickness in the user manual.
Inspect the part for mechanical damage. Perceptible cracks (more than 1 mm), chips, grooves and other types of deformation can lead to the destruction of the disc in case of heavy braking. Brake discs with serious defects are not allowed to be used.
Determine the beat of the disk. In the service, you can use a micrometer, which can be used to determine the amplitude of the beating of the brake disc. If the values exceed 100 microns, such a disc in the process of use will create noticeable vibrations, wear out the brake pads more quickly and reduce the braking efficiency.
If your vehicle exhibits any of these symptoms, bad system components should be replaced. This will not only increase your safety while driving a car, but will also allow you to save on repairs in the event of disc failure or replacement of brake pads, which will wear out faster when working with a damaged disc.
What is the price of replacing brake discs?
The cost of brake repair will greatly depend on the model of your car and the quality of the selected spare parts.

Specialists of service centers advise to change andbrake pads, as their wear can reduce the efficiency of the braking system.
The price of worksthe cost of replacing these parts in Ukraine ranges from $30 to $100 per disc.
