Parking Brake Shoe: Testing and Inspection

PARKING BRAKE SHOE INSPECTION





1. MEASURE BRAKE SHOE LINING THICKNESS
Using a ruler, measure the thickness of the shoe lining.
Standard thickness: 2.5 mm (0.098 inch)
Minimum thickness: 1.0 mm (0.039 inch)
If the lining thickness is at the minimum or less, or if there is severe, uneven wear, replace the brake shoe.




2. MEASURE CLEARANCE BETWEEN PARKING BRAKE SHOE AND LEVER
Using a feeler gauge, measure the clearance.
Standard clearance: Less than 0.35 mm (0.0138 inch)





If the clearance is not within the specification, replace the shim with one of the correct size.
3. IF NECESSARY, REPLACE SHIM





a. Using a screwdriver, remove the C-washer.
b. Remove the parking brake shoe lever, and install the correct size shim.





c. Install the parking brake shoe lever with a new C-washer.
d. Remeasure the clearance.
