Component Tests and General Diagnostics

PARKING BRAKE: PARKING BRAKE ASSEMBLY: INSPECTION

1. INSPECT BRAKE DISC INSIDE DIAMETER

(a) Using a brake drum gauge or an equivalent tool, measure the inside diameter of the disc.





Standard inside diameter:

173 mm (6.81 in.)

Maximum inside diameter:

174 mm (6.85 in.)

If the inside diameter is more than the maximum, replace the rear disc.

2. INSPECT PARKING BRAKE SHOE LINING THICKNESS

(a) Using a ruler, measure the thickness of the parking brake shoe lining.





Standard thickness:

3.5 mm (0.138 in.)

Minimum thickness:

1.0 mm (0.0394 in.)

If the lining thickness is less than the minimum, or if there is severe or uneven wear, replace the parking brake shoe assembly.

NOTICE:
Always replace both right and left parking brake shoes together.

3. INSPECT BRAKE DISC AND PARKING BRAKE SHOE LINING FOR PROPER CONTACT

(a) Apply chalk to the inside surface of the disc, then grind down the brake shoe lining to fit the disc.





If the contact between the disc and the brake shoe lining is incorrect, repair it using a grinder or replace the parking brake shoe assembly.

NOTICE:
* Always replace both right and left parking brake shoes together.
* Wipe off the chalk after inspection.
