Parking Brake Assembly - Inspection

1. Inspect brake disc inside diameter

2. Inspect parking brake shoe lining thickness

3. Inspect brake disc and parking brake shoe lining for proper contact

​

1. Using a brake drum gauge or equivalent, measure the inside diameter of the disk.

   Standard inside diameter:

   210mm (8.27 in.)
   

   Maximum inside diameter:

   211mm (8.30 in.)
   

1. Using a ruler, measure the thickness of the shoe lining.

   Standard inside diameter:

   4.0mm (0.158 in.)
   

   Maximum inside diameter:

   1.0mm (0.039 in.)
   

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

1. Apply chalk to the inside surface of the disc, then grind down the brake shoe lining to fit.
   If the contact between the brake disc and the shoe lining is improper, repair it using a brake shoe grinder or replace the brake shoe assembly.
