WARNING: THE SELF ADJUSTING FEATURE OF THIS PARKING BRAKE LEVER ASSEMBLY CONTAINS A CLOCK SPRING LOADED TO APPROXIMATELY 30 POUNDS. CARE MUST BE TAKEN TO PREVENT EXCESSIVE JARRING OF THE ASSEMBLY. DO NOT RELEASE THE SELF ADJUSTER LOCKOUT DEVICE BEFORE INSTALLING CABLES INTO THE EQUALIZER. KEEP HANDS OUT OF SELF ADJUSTER SECTOR AND PAWL AREA. FAILURE TO OBSERVE CAUTION IN HANDLING THIS MECHANISM COULD LEAD TO SERIOUS INJURY.

When repairs to the hand lever assembly or cable system are required the self adjuster must be reloaded and locked out.

SELF ADJUSTING PROCEDURES

TO RELOAD SELF ADJUSTER

Remove ash receiver or courtesy light from rear of center console to gain access to self adjuster. Also, remove carpet from sides of console.

Pull on equalizer/output cable to wind up spring(requires greater than 30 pounds effort). Continue until self adjuster lockout pawl is positioned about midway on the self adjuster sector (Fig. 4). Rotate lockout pawl into self adjuster sector by turning allen screw clockwise. Rotating lockout device requires very little effort. Do not force or failure of lockout device will occur.

When repairs are complete, adjust rear brakes before adjusting parking brake. On drum-in-hat type of rear disc brake adjust shoe diameter to 171.5 mm (6.75 inch).

ADJUST PARKING BRAKE

Be sure that the cables are properly assembled to the equalizer bracket prior to cable adjustment.

Insert a 7/32 inch allen wrench into hex socket and turn counter-clockwise through approximately 15° of rotation (Fig. 5). In turning lockout device, self adjuster release is a loud snapping noise followed by reaching a more felt than heard detente. Very light effort is required to seat lockout arm into detente. Follow through to the detente is important in preventing the lockout rod from rattling.

Note: The parking brake handle can be in any position when releasing self adjuster.

Cycle lever to position cables. Rear wheels should rotate freely without dragging.

REAR PARKING BRAKE CABLE REMOVAL

The rear brake cables are attached to rear connectors.

Should it become necessary to remove either parking brake cable for installation of a new cable, proceed as follows:

Fig. 5 Self Adjusting Parking Brake Lever Assembly

With vehicle jacked up on a suitable hoist, remove wheel and tire assembly.

Back off cable adjusting nut to provide slack and disconnect rear brake cable from connector.

DRUM BRAKES

Disconnect cable from park brake lever.
