PARKING BRAKE LEVER STROKE CHECK AND
ADJUSTMENT

M1361000900362

1. Pull the parking brake lever with a force of approximately

200 N (45 pounds) and count the number of notches.

Standard value: 5

− 7 notches

2. If the parking brake lever stroke is not within the standard

value, adjust as described below.

(2) Remove the console inner box tray and plate (Refer to

GROUP 52A, Floor Console Assembly

P.52A-9

), and

then loosen the adjusting nut to move it to the cable rod
end so that the cable will be free.

(3) Remove the rear wheels, and then remove the

adjustment hole plug on the brake disc.

(4) Use a flat-tip screwdriver to turn the adjuster in the

direction of the arrow (the direction which expands the
shoe) so that the disc will not rotate by hand. Return the
adjuster five notches in the direction opposite to the
direction of the arrow.

(5) Install the rear wheels, and then tighten the wheel nuts to

98

± 10 Nm (73 ± 7 ft-lb).

CAUTION

Be careful that the parking brake lever stroke should be
within the standard value. If the stroke is too short, brake
dragging can be caused.

(6) Turn the adjusting nut to adjust the parking brake lever

stroke to the standard value. After adjustment, check that
the adjust nut and the cable rod is not loose.

(7) Release the parking brake and turn the rear wheels to

check that the rear brakes are not dragging.

3. If either of the parking brake cables is replaced, adjust the

parking brake lever stroke as described previously, pull the
parking brake lever 10 times with approximately 200 N (45
pounds) to eliminate the initial slack of the cable. Then
adjust the parking brake lever stroke as described
previously again.
