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 severe and uneven wear, replace the brake shoe.

3.

MEASURE BRAKE DISC INSIDE DIAMETER

Using a brake drum gauge or equivalent, measure the inside di-
ameter of the disc.

Standard inside diameter: 210 mm (8.27 in.)
Maximum inside diameter: 211 mm (8.31 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
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.

5.

MEASURE CLEARANCE BETWEEN PARKING
BRAKE SHOE AND LEVER

Using a feeler gauge, measure the clearance.

Standard clearance: Less than 0.25 mm (0.010 in.)

If the clearance is not within the specification, replace the shim
with one of the correct size.
