cause failure of the braking system. Dispose of in
accordance with Federal, state and local codes.
Attach a short length of clear hose to the caliper bleed
valve and insert the other end into a suitable clean con-
tainer containing fresh, clean brake fluid (Ref. Fig. 6).
Check the fluid level in the master cylinder frequently

Starting with the passenger side rear brake and going
to the driver side rear brake, bleed the brakes using the
following procedure:
The bleeder valve at the caliper must be closed at the
end of each stroke and before the brake pedal is
released to insure that air cannot enter the system. It is
also important that the brake pedal be returned to full
'up' position.
Open the bleeder valve and have an assistant depress
brake pedal gently until fluid flows into container. Close
the bleeder valve and have the assistant slowly release
the brake pedal. Repeat the process until no bubbles
can be seen leaving the bleeder valve. Close the valve
and repeat at other side. After bleeding, check fluid
level using a mechanics mirror and a flashlight. Add
fluid if the level has fallen below 1/4" from the top of the
reservoir and inspect for visible fluid leaks.
PARKING BRAKE
The rear brake includes a parking feature consisting of a
wheel brake lever and strut. The wheel brake lever is
applied by a cable attached to the parking brake lever
(hand or foot operated). The parking brake is used to
retain the vehicle when stationary. It may also be used
as an emergency brake in the event of hydraulic system
failure. Parking brake is attached with reed switch, which
is activated by magnetic field. The magnet, which is
attached to the lever, opens and closes the reed switch.
Switch on the park brake lever turns on the warning
buzzer when the lever is up.
The hand operated parking brake lever is located at the
right side of the driver in the console between the front
seats. when parking brake lever is in vertical position the
brake is engaged, if it is in horizontal position then brake
is released (Ref. Fig. 7).
Lubrication
When lubricating parking brake, be sure to use the rec-
ommended dry spray lubricant. Commercial grease can
attract dirt and accelerate wear.
The hand operated parking brake lever requires periodic
lubrication with a dry graphite or molybdenum disulfide
lubricant. Raise the lever and spray into the underside to
access the pivot arm and ratchet mechanism of the park-
ing brake. See Section A - Periodic Service Schedule for
recommended lubrication schedule.
