from the backing plate.

handbrake cable flange from the rear of the backing
plate and remove the cable from the vehicle.

(6) Inspect the rear handbrake cables for chafing
or broken strands. Renew the cables if damage is
evident.

Installation is a reversal of the removal procedure
with attention to the following points:

(1) Ensure that the handbrake cable clamps are
correctly installed. (2) On drum brake models, install the
handbrake
cable to the backing plate by carefully tapping the
flange on the handbrake cable. Ensure that the cable is
not damaged. (3) Adjust the handbrake cable as described
under the Brake Adjustments heading.
9. BRAKE ADJUSTMENTS

FRONT AND REAR DISC BRAKES
The disc brakes are self adjusting and no manual
adjustment is required or provided.

REAR DRUM BRAKES
Depress the handbrake lever button, apply and
release the handbrake lever several times to adjust the
rear brake shoes.

HANDBRAKE
(1) Raise the rear of the vehicle and support it
on chassis stands. (2) Remove the carpet square from the rear of
the console. Remove the retaining screws from the
front and rear of the rear console section and manoeu-
vre the rear console from the vehicle. (3) Tighten the adjusting nut until the hand-
brake lever pull is between 7-11 notches. (4) Check that the rear wheels are not binding. If
the rear wheels do not rotate freely refer to the Brakes
Trouble Shooting for possible causes.
(5) With the ignition switched On, check that
the handbrake warning lamp is extinguished when the
lever is fully released. (6) Lower the vehicle to the ground and test the
handbrake on an incline.
10. BRAKE PEDAL

TO REMOVE AND INSTAL
(1) Working inside the vehicle remove the re-
taining clip from the clevis pin and remove the clevis
pin connecting the brake pedal to the pushrod.

(2) Remove the nut from the pivot bolt and
withdraw the brake pedal pivot bolt.
(3) Maneuver the brake pedal from the mount-
ing bracket. (4) Remove the spring from the brake pedal.
(5) Inspect the return spring for breakage or
fatigue. Renew as required.
(6) Inspect the pedal pivot bolt for damage or
wear. Renew as required. (7) Inspect the brake pedal for wear, cracks or
fatigue. Renew as required. Installation is a reversal of the removal procedure
with attention to the following points:

(1) Sparingly lubricate the pedal pivot bolt and
clevis pin with a suitable grease. (2) Ensure that the brake pedal pivot bolt is
correctly located in the pedal bracket. (3) Ensure that the clevis pin is inserted fully
through the clevis and the retaining clip is correctly
installed. (4) Check and if necessary adjust the brake
pedal height and stop lamp switch as described below.
TO ADJUST PEDAL HEIGHT

The dimension for the pedal height is measured at
right angles from the floor, with the carpet pulled
back, to the centre of the pedal pad.

(1) Working inside the ve hicle, disconnect the
wiring from the stop lamp switch.
(2) Loosen the stop lamp switch locknut and
position the switch away from the brake pedal. (3) Loosen the locknut on the brake pedal push-
rod and adjust the pushrod to achieve a pedal height
of 155-165 mm on manual transaxle models or
164-174 mm on automatic transaxle models. Tighten
the locknut. (4) Adjust the stop lamp switch as described
under the following heading.

mension H = brake pedal height, Dimension C = stop
lamp switch clearance, Dimension F - brake pedal free
play.
TO ADJUST STOP LAMP SWITCH
(1) Loosen the stop lamp switch locknut and
disconnect the wiring from the switch.
(2) Adjust the stop lamp switch to achieve a
clearance of 0.3-1.0 mm between the pedal stop and
the threaded end of the switch. (3) Tighten the locknut and connect the wiring
to the switch. Ensure that the stop lamps are off when
the pedal is released.
(4) Ensure that the pedal free play is 1.0-3.00
mm after adjustments have been completed.
11. HYDRAULIC SYSTEM

TO BLEED
Bleeding the hydraulic system should only be
necessary when some portion of the hydraulic system
has been disconnected or fluid has been drained,
allowing air to enter the system.

The brake fluid in the hydraulic system should be
changed every 30 000 km or 18 months. The proce-
dure for changing the brake fluid and bleeding the
hydraulic system are simila r with attention to the
notes in the text.

There are four points in the system where bleeder
valves are installed, one on each front caliper and one
on each rear wheel cylinder or rear caliper.

14. Fill the fluid reservoir with clean hydraulic
brake fluid and maintain at least one third full
throughout the entire operation. 15. Attach a transparent hose to the bleeder
valve on the left rear cali per and immerse the other

end of the hose in a small amount of clean brake fluid
contained in a clean glass jar held higher than the
bleeder valve.

14. Unscrew the bleeder valve one
complete turn.
15. Have an assistant depress the brake
pedal slowly to the full extent of its travel. Close
the bleeder valve and allow the brake pedal to
r e t u r n w i t h o u t assistance. 16. Repeat operations (3) and (4) until
a con stant stream of fluid, without any air
bubbles, is being discharged into the gl ass jar,
hold the brake pedal down and tighten the
bleeder valve.
