INSPECTION
1. Inspect disassembled parts.
Inspect the disassembled parts for wear, rust or damage.





2. Measure brake shoe lining thickness.
Using a ruler, measure the thickness of the shoe lining.
Standard thickness: 4.0 mm (0.157 inch)
Minimum thickness: 1.0 mm (0.039 inch)
If the lining thickness is at the minimum thickness or less, or if there is severe and uneven wear, replace the brake shoe.





3. Measure brake disc inside diameter.
Using vernier calipers, measure the inside diameter of the disc.
Standard inside diameter: 230 mm (9.06 inch)
Maximum inside diameter: 231 mm (9.09 inch)
Replace the disc if the inside diameter is at the maximum value or more. Replace the disc or grind it with a lathe if the disc is scored or is worn unevenly.





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





5. 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.
Thickness:
0.3 mm (0.012 inch)
