PEDAL STROKE

When parking brake pedal is operated with a force of 200 N (20.4 kg, 44.9 lb), make sure the parking
brake pedal stroke is within the specified number of notches. (Check it by listening and counting the
ratchet clicks.)

Make sure that brake warning lamp comes on when parking brake pedal is depressed with in one notch.
INSPECT COMPONENTS

Make sure the components are installed properly (check for looseness, backlash, etc.).

Check parking brake pedal assembly for bend, damage and cracks, and replace if necessary.

Check cable for wear and damage, and replace if necessary.

Check parking brake warning lamp switch for malfunction, and replace if necessary.
ADJUSTMENT
1. Insert a deep socket wrench to rotate adjusting nut and loosen
cable sufficiently. Then, return pedal.
2. Remove tires from vehicle with power tool.
3. Using wheel nuts, fix disc rotor to hub and prevent it from tilting.
4. Remove adjusting hole plug installed on disc rotor. Using a flat- bladed screwdriver, turn adjuster to clockwise in the figure until
disc rotor is locked. After locking, turn adjuster to opposite direc-
tion by 5 or 6 notches.
5. Rotate disc rotor to make sure that there is no drag. Then install adjusting hole plug.
6. After adjusting the clearance of rear shoes, with no drag on rear brake, adjuster cable as follows:
a. Operate pedal 10 or more times with a force of 490 N (50 kg, 11 0 l b ) .
b. Depress pedal until a deep socket wrench can be inserted. Insert deep socket, and rotate adjusting nut to adjust pedal stroke.
CAUTION:
Do not reuse adjusting nut after removing it.
c. When parking brake pedal is operated with a force of 200 N (20.4 kg, 44.9 lb), make sure the stroke is within the specified number of notches. (Check it by listening and counting the ratchet clicks.)
d. With parking brake pedal completely returned, make sure there is no drag on rear brake. Pedal stroke : 4
− 5 notches

Refer to PB-6, "Components" , and apply brake grease to the specified points during assembly.

Assemble adjuster so that threaded part expands when rotating
it in the direction shown by the arrow.

Shorten adjuster by rotating it.

When disassembling adjuster, apply PBC (Poly Butyl Cuprysil)
grease or silicone based grease to the threads.

After replacing brake shoes or disc rotors, or if brakes do not
function well, perform break-in operation as follows.
1. Install in the reverse order of the removal.
2. Adjust parking brake pedal stroke to the specified stroke. Refer to PB-3, "
ADJUSTMENT" .
3. Perform parking brake break-in (drag run) operation by driving the vehicle under the following conditions:
4. After break-in operation, check pedal stroke of parking brake. Readjust if it is no longer at the specified stroke. Refer to PB-3, "
ADJUSTMENT" .

To prevent lining from getting too hot, allow a cool off period of approximately 5 minutes after every
break-in operation.

Do not perform excessive break-in operations, because it may cause uneven or early wear of lining. Drive forward
