Checking the thickness of the brake linings

Front disc brake pads wear faster than rear drum brakes. However, it is advisable, with regular checks, to check the brake linings of all 4 wheels.

Front disc brakes

1. Mark the position of the front wheel relative to the hub with paint, so that the balanced wheel can be installed in its original position. Loosen wheel bolts.

2. Put the car on stands, remove the front wheel. If the pads are relatively new, the test can only be done on one front wheel. In this case, the right front wheel is removed. Due to approximately the same wear, it is possible to draw a conclusion about the thickness of the lining and the other front wheel.



3. Check by eye the thickness of the pads together with the metal plate, behind, through the brake support. If in doubt, remove the brake pads and check the thickness (A) caliper. The figure shows the outer brake pad. Inner lining (on the back of the brake disc) check in the same way.

4. The wear limit of the front brake pads has been reached if the thickness of the brake pad (along with the plate) is 7 mm.

Rear wheel drum brakes

1. Place the machine on stands.




2. Remove the plug on the rear brake caliper (arrow) and shine a flashlight into the hole. The wear limit has been reached if the lining at this point has a thickness of 1.0 mm (without block). If in doubt, remove the brake drum and measure the lining thickness. When checking the lining thickness, pay attention to the absence of brake fluid or oil on the brake linings. In this case, replace the brake linings immediately.

3. If the wear limit is reached, replace the pads. Replace lining of the entire bridge at once.

Attention! 1 mm of brake lining wear corresponds to approximately 1,000 km of run, even under unfavorable driving conditions. Usually pads last a long time. With a front disc brake pad thickness of approx. 10.0 mm (along with the plate) they are still enough for at least 3000 km of run.
