Disassembling the parking brake
1. Remove the rear wheel.
2. Remove the rear caliper assembly.
a) Unscrew the two mounting bolts and remove the rear caliper assembly.
b) Hang the caliper so as not to stretch the hose.

b) Remove the return spring from the rear shoe.
c) Disconnect the parking brake cable from the parking brake lever.
8. Remove the lock washer and parking brake lever from the brake shoe.
Checking the parking brake
1. Check the removed parts for wear, rust or damage.
2. Using a ruler, measure the thickness of the brake shoe linings.
- Standard thickness is 2.0 mm
- Minimum thickness - 1.0 mm
Replace the brake pads if the brake lining thickness is less than the minimum permitted or if uneven lining wear is detected.
3. Using a caliper, measure the inside diameter of the brake disc.
- Standard - 170 mm
- Maximum allowable - 171 mm
Replace the brake disc if the inner diameter is greater than the maximum allowable.
4. Check the tightness of the brake shoe lining to the drum (disc).
If the contact between the working surfaces is poor, replace the brake pads.
5. Using a feeler gauge, measure the gap between the brake shoe and the parking brake lever.
- Maximum allowable gap is 0.35 mm
If the gap does not meet the technical requirements, then select an adjusting washer of the required thickness from the values given in the table.
