On-Vehicle Service

AFS00182

PEDAL STROKE

●

When parking brake pedal is operated with a force of 196 N (20 kg, 44 lb), make sure the stroke is within
the specified number of notches. (Check it by listening and counting the ratchet clicks.)

INSPECT COMPONENTS

●

Make sure the components are attached 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

●

To perform adjustment operations, remove tire from the vehicle with power tool.

1.

Insert a deep socket wrench to rotate adjusting nut and loosen
the cable sufficiently. Then, return the pedal to the free height.

2.

Using wheel nuts, fix the disc to the hub and prevent it from tilt-
ing.

3.

Remove adjusting hole plug installed on the disc rotor. Using a
screwdriver, turn the adjuster as shown in the figure until the
disc rotor is locked. After locking, turn the adjuster in the oppo-
site direction by 5 or 6 notches.

4.

Rotate the disc rotor to make sure there is no drag. Install the
adjusting hole plug.

5.

Adjust cable as follows:

a.

Operate pedal 10 or more times with a force of 294 N (30 kg, 66
lb).

b.

Rotate adjusting nut with deep socket to adjust pedal stroke.

NOTE:
Do not reuse the adjusting nut after removing it.

c.

When parking brake pedal is operated with a force of 196 N (20 kg, 44 lb), make sure the stroke is within
the specified number of notches. (Check it by listening and counting the ratchet clicks.)

d.

With the pedal completely returned, make sure there is no drag on the rear brake.

INSPECTION AFTER REMOVAL

Lining Thickness Inspection

●

Check thickness of lining. 

Drum Inner Diameter Inspection

●

Check drum inner diameter.

Other Inspections

●

Check shoe sliding surface for excessive wear and damage.

●

Check anti-rattle pin for excessive wear and corrosion.

●

Check return spring for sagging.

●

Does the adjustor move smoothly?

●

Check either visually or with a vernier caliper to see if there is any excessive wear, cracks, or damage
inside the drum.

INSTALLATION

Be careful of the following.

●

Refer to “Component Parts Location” and apply brake grease to the specified points during assembly.

●

There is difference of the adjusters orientation difference
between left and right. Assemble the adjuster so that threaded
part expands when rotating it in the direction shown by the
arrow.

●

Shorten adjuster by rotating it.

●

When disassembling the adjuster, apply PBC (Poly Butyl Cupry-
sil) 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.

Adjust the parking brake pedal stroke to the specified stroke.

2.

Perform break-in (drag run) operation by driving the vehicle
under the following conditions:

3.

After break-in operation, check lever stroke of the parking brake. Readjust if it is no longer at the specified
stroke.

●

To prevent the 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 the lining.
