Checking the thickness of the lining of the brake shoes of drum brakes

1. Remove the brake drum.

2. At the point of greatest wear, measure the thickness of the brake pad lining (pic. 15.28).



Nominal thickness: 4.38 mm Minimum thickness: 1.0 mm

If the lining thickness is less than the minimum or uneven wear is observed, replace the brake pads. When replacing the brake pads, it is necessary to change them both on the left and on the right side of the car in order to prevent uneven braking of the right and left wheels. With a significant difference in the degree of wear (thickness) brake pads on the left and right wheels, check the operation of the piston of the working brake cylinder.
