INSPECTION
1. INSPECT REAR DISC
(a) Using a brake drum gauge or equivalent, measure the inside diameter of the disc.
Standard inside diameter: 190 mm (7.48 in.)
Maximum inside diameter: 191 mm (7.52 in.)
If the inside diameter is more than the maximum, replace the disc.
2. INSPECT PARKING BRAKE SHOE LINING THICKNESS
(a) Using a ruler, measure the thickness of the shoe lining.
Standard thickness: 2.4 mm (0.094 in.)
Minimum thickness: 1.0 mm (0.039 in.)
If the lining thickness is less than the minimum, or if there is severe or uneven wear, replace the brake shoe.
NOTICE: Always replace both the 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 the brake shoe lining on the disc until full contact is achieved. If the disc and brake shoe lining do not have full contact, use a brake shoe grinder or replace the brake shoe.
(b) After the inspection, wipe chalk off the inside surface of the disc and lining surface.
