Component Tests and General Diagnostics

PARKING BRAKE (REAR DISC BRAKE)

A: INSPECTION

Inspect brake linings and drums of both sides of the rear brake at the same time by removing brake drums.

1. Inspect brake shoes for damage or deformation and check brake linings for wear.





NOTE: Always replace both primary and secondary brake shoes for the left and right wheels at the same time.





2. Check brake drum for wear, dents or other damage. If the inside surface of brake drum is streaked, correct the surface with emery cloth (#200 or more). If it is unevenly worn, tapered, or the outside surface of brake drum is damaged, correct or replace it.
3. If the deformation or wear of back plate, shoe, etc. is noticeable, replace them.
4. When the shoe return spring tension is excessively weakened, replace it, taking care to identify upper and lower springs.
5. Measure brake disc inside diameter. If the disc is scored or worn, replace the brake disc.
Disc inside diameter:
Standard 170 mm (6.69 inch)
Service limit 171 mm (6.73 inch)
6. Measure the lining thickness. If it exceeds the limit, replace shoe assembly.
Lining thickness:
Standard 3.2 mm (0.126 inch)
Service limit 1.5 mm (0.059 inch)
