Inspection and Repair

Parking Brake Lining Inspection

Check the shoe assemblies for wear by removing the
brake drum rotor.
Replace the shoe assemblies if the lining thickness is less
than 1.0 mm (0.039 in).

Minimum limit: 1.0 m (0.039 in)

Parking Brake Rotor (Drum) Inspection

Refer to “Rear Disc Brakes” in Section 5A2 for the
inspection procedure of the rotor (drum).

Parking Brake Adjustment

1. Adjustment of parking brake assembly

D

Prior to lever stroke adjustment, adjust the rear
brake shoe/rotor (drum) gap. Perform this
procedure by loosening the adjusting nut of the
equalizer.

a. Remove the adjusting hole plug (rubber) and turn

the shoe adjusting screw downward using a small
screwdriver so that the shoes will expand until they
get into close contact with the rotor. (Turn down the
adjusting screw notch by notch until the rotor does
not turn.)

b. Turn the adjusting screw in the opposite direction

(upward) until the rotor can be turned lightly.
Standard number of notches to turn upward: 7 or 8.

Turn the rotor in order to ensure that there is no
brake dragging.

2. Adjustment of parking brake cable

a. Turn the equalizer nut so that the parking brake

lever travels 6 or 7 notches when pulled up with a
force of 30 kg (66 lb).

b. Make sure that there is no brake dragging and

tighten the cable lock nut.

Torque : 6 N·m (52 lb in)

3. Break–in of parking brake shoe

D

When poor braking  is felt, or just after replacement
of parking brake shoes, be sure to conduct the
break–in procedure by driving the vehicle as
follows:

a. Forward 50 km/h (30 mph) 

×

 400 m (about 30

seconds) with a lever pull force of 15 kg (33 lb).

b. Backward 10 km/h (6 mph) 

×

 50 m (about 18

seconds) with a lever pull force of 15 kg (33 lb).

NOTE: Break–in procedures must be performed under
safe conditions and traffic rules.

D

If the braking effect remains poor after the break–in,
wait for some time until parking brake shoe cools
down and repeat procedures a. and b. noted above.

D

On completion of break–in, inspect the parking
brake lever stroke, and if the lever does not come
within the specified number of notches when pulled
up, readjust.

D

Excessive break–in may cause premature wear of
the parking brake lining.
