PARKING BRAKE: PARKING BRAKE ASSEMBLY: INSPECTION

INSPECTION





1. INSPECT BRAKE DISC INSIDE DIAMETER
(a) Using a brake drum gauge or the equivalent, measure the inside diameter of the rear disc.
Standard inside diameter:
210 mm (8.268 in.)
Maximum inside diameter:
211 mm (8.307 in.)
If the inside diameter is greater than the maximum, replace the rear disc.





2. INSPECT PARKING BRAKE SHOE LINING THICKNESS
(a) Using a ruler, measure the thickness of the shoe lining.
Standard thickness:
4.0 mm (0.157 in.)
Minimum thickness:
1.0 mm (0.039 in.)
If the lining thickness is equal to or less than the minimum value, or if there is any severe or uneven wear, replace the brake shoe.





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 so that they fit together properly.
If the contact between the disc and the shoe lining is improper, repair it using a brake shoe grinder or replace the brake shoe assembly.
