ON-VEHICLE SERVICE
Adjustment
Abnormal parking brake operation may be caused by the worn brake shoe, incorrect brake shoe clearance
adjustment, incorrect parking brake control mechanism stroke or incorrect parking brake component
installation. Perform the following procedures to adjust the parking brake control mechanism stroke:

CAUTION

 The rear brake shoe of this model is equipped with gear type automatic adjustment mechanism, so it is
not necessary to adjust the brake shoe clearance manually. When the brake clearance exceeds the
specified value, depress the brake pedal to adjust it through the automatic adjustment unit installed
between the two brake shoe linings.

1. Check the parking brake control mechanism stroke.


a. Pull up the parking brake control mechanism 3 to 4 times with a force of 260 ± 20 N, and count the
clicking sounds.
Standard: 4 to 7 clicking sounds (no rear parking brake stuck)
2. Support and raise the vehicle to the proper height.
3. Remove the rear wheel (See page 23-10).
4. Remove the rear brake drum assembly (See page 25-39).
5. Remove the auxiliary fascia console assembly (See page 43-10).
6. Adjust the parking brake control mechanism stroke:
a. Fully release the parking brake control mechanism.
b. Pull up the parking brake control mechanism until 3 or
4 clicking sounds are heard, then tighten the parking
brake control mechanism locking nut.
(Tightening torque: 8 ± 1 N·m)

RA19260020

c. After tightening the parking brake control mechanism locking nut, pull the parking brake control
mechanism 3 times with a force of 200-300 N to eliminate the remaining force of the cable.
d. Correct judgment method: after adjustment, completely release the parking brake control mechanism
and rotate the rear wheel by hand.
OK: Rear wheel can be rotated freely without dragging.
Pull up the parking brake control mechanism until a clicking sound is heard. There is resistance when
rotating the rear wheel by hand. Pull up the parking brake control mechanism until 2 clicking sounds are
heard and the rear wheel cannot rotate.
e. When operating the parking brake control mechanism, check that the brake warning light illuminates at
the first click.
OK: Parking brake warning light always illuminates at the first click.
f. If the result is not as specified, repeat the above procedures until the parking brake control mechanism 26
stroke is proper.
7. Install the auxiliary fascia console assembly (See page 43-10).
