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 a brake drum gauge or equivalent, measure the inside diameter of the disc.
Standard inside diameter: 210 mm (8.27 inch)
Maximum inside diameter: 211 mm (8.31 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 worn unevenly.
4. INSPECT PARKING BRAKE SHOE 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.
