How often do the brake discs change?

• Brake pipelines . Special fluid is used in hydraulic systems of pressure transmission from pedal to the brake. It is stored in the main cylinder and enters the calipers through the brake lines.
• brake pads - pressed against the disk and create the friction required to slow and stop the car. They can be made of metal, ceramics or organic material and be ventilated or non -ventilated.
• brake discs - have a circle shape and attached to the wheel, taking kinetic energy and turning it into thermal, which is then absorbed and scattered.
• calipers - press brake pads to disks to slow down and stop the car.

When to change the brakes?

If you do not know the accurate mileage of your car, General rule is to inspect the braking system annually or every 30000 - 50000 km. The timing of replacement of pads is 15000 - 30000 km, and the discs should be changed every 80000 - 120,000 km.

numbers may vary depending on how you drive a car.If you carry heavy loads or spend a lot of time in traffic jams, your brakes will wear much faster than in the car used for driving on the highway. In addition, if you are an active driver, often and strongly inhibit, the components will wear out much faster.

How to determine the wear of the brake discs?

As a driver, you can first feel in the process of control that with your brakes something is wrong. If you notice one of these signs then most likely your brake disks are very worn:

• when pressed on the brake pedal there are strong vibrations;
• regular pedal beating in the braking process;
• A metal creak that can change the tone as the wheels rotate.

These are implicit, but clear signs that you should diagnose the brake system as soon as possible and replace worn out components.

If you have the opportunity to remove the wheel, remove the pads, caliper and inspect the entire surface of the brake disk, you can identify the problem without traveling to the service. There are several methods :

Check the check labels - manufacturers, as a rule, apply special channels, which can determine the degree of disk wear by condition. If in the area of ​​contact of the disk with the pad the label is completely gone, it is necessary to replace the part with a new one.

measure the thickness of the disk . You can do this with a caliper. But what should be the thickness of the brake disc? In most cases, the use of the thickness of the edge of the brake disk can be found in the guide to use.

Inspect the part like mechanical damage . Fasten cracks (more than 1 mm), chips, furrows and other types of deformation can lead to the destruction of the disk in the case of strong inhibition. The brake discs with serious defects are not allowed to be used.

Determine the beating of the disk . In the service you can use a micrometer that can determine the amplitude of the braking disc. If the value exceeds 100 microns, such a disk will create noticeable vibrations in the process, wear out the brake pads faster and impair the braking efficiency.

If your car has any of these features, the bad components of the system should be replaced. This will not only increase your safety at the wheel of the car, but also save on repair in the event of a disk failure or replacement of brake pads, which will wear out faster when working with a spoiled disk.
