REMOVAL OF REAR BRAKE
1. INSPECT SHOE LINING THICKNESS
Remove the inspection hole plug, and check the shoe lin-
ing the thickness through the hole.
If less than minimum, replace the shoes.
Minimum thickness: 1.0 mm (0.039 in.)
2. REMOVE REAR WHEEL
3. REMOVE BRAKE DRUM
HINT: If the brake drum cannot be removed easily, per-
form the following steps.
(a) Insert a bent wire or an equivalent through the hole
in the brake drum, and hold the automatic adjusting

(c) Disconnect the anchor spring from the front shoe
and remove the front shoe.
(d) Remove the anchor spring from the rear shoe.
7. DISCONNECT BRAKE TUBE FROM WHEEL CYL-
INDER
Using SST, disconnect the brake line. Use a container to
catch the brake fluid.

2. MEASURE BRAKE SHOE LINING THICKNESS
Standard thickness: 5.0 mm (0.197 in. )
Minimum thickness: 1 .0 mm (0.039 in.)
If the shoe lining is less than minimum or shows signs of
uneven wear, replace the brake shoes.
HINT: If any of the brake shoes have to be replaced, re-
place all of the rear shoes in order to maintain even brak-
ing. 9. IF NECESSARY, DISASSEMBLE WHEEL CYLINDER
Remove the following parts from the wheel cylinder.
wTwo boots
wTwo pistons
wTwo piston cups

3. MEASURE BRAKE DRUM INSIDE DIAMETER
Standard inside diameter: 228.6 mm (9.000 in.)
Maximum inside diameter: 230.6 mm (9.079 in.)
If the drum is scored or worn, the brake drum may be lathed
to the maximum inside diameter.
INSPECTION AND REPAIR OF REAR
BRAKE COMPONENTS
1. INSPECT DISASSEMBLED PARTS
Inspect the disassembled parts for wear, rust or damage. 8. REMOVE WHEEL CYLINDER
Remove the two bolts and the wheel cylinder.

5. MEASURE CLEARANCE BETWEEN 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 specification, replace the shim
with one of the correct size. 4. INSPECT REAR BRAKE LINING AND DRUM FOR
PROPER CONTACT
If the contact between the brake lining and drum is improp-
er, repair the lining with a brake shoe grinder, or replace
the brake shoe assembly.
6. IF NECESSARY, REPLACE SHIM
(a) Remove the parking brake lever, and install the cor-
rect size shim.
(b) Install the parking brake lever with a new C±washer.
(c) Remeasure the clearance.

8. CHECK OPERATION OF AUTOMATIC ADJUSTING
MECHANISM
(a) Move the parking brake lever of the rear shoe back
and forth, as shown. Check that the adjuster turns.
If the adjuster does not turn, check for incorrect installation
of the rear brakes.
(b) Adjust the adjuster length to the shortest possible
amount. 7. INSTALL FRONT SHOE
