Checking the parking brake
1. Check the removed parts for wear, rust or damage.
2. Using a ruler, measure the thickness of the brake pads.
- Standard thickness - 2.0 mm
- Minimum thickness - 1.0 mm
Replace the brake pads if the brake lining thickness is less than the minimum allowable or uneven lining wear is detected.
3. Using a vernier caliper, measure the inside diameter of the brake disc.
- Standard - 170 mm
- Maximum allowable - 171 mm
Replace the brake disc if the inside diameter is larger than the maximum.
4. Check the fit of the brake shoe lining to the drum (disk).
If the contact between the working surfaces is poor, then replace the brake pads.
5. Using a feeler gauge, measure the clearance between the brake shoe and the parking brake lever.
- The maximum allowable gap is 0.35 mm
If the gap is not within specifications, then fit a shim of the desired thickness from the values given in the table.
