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 in.)
Minimum thickness: 1.0 mm (0.039 in.)
If the lining thickness is at the minimum thickness or less, or if
there is extremely uneven wear, replace the brake shoe.
3. MEASURE BRAKE DISC INSIDE DIAMETER
Using a vernier calipers, measure the inside diameter of the
disc. Standard inside diameter: 230 mm (9.06 in.)
Maximum inside diameter: 231 mm (9.09 in.)
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 in.)
If the clearance is not within the specification, replace the shim
with one of the correct size.
