REMOVAL & INSTALLATION
See Figure 1
- Disconnect battery ground cable.
- Disconnect brake light switch harness from rear of switch.
- Remove the pushrod retainer and nylon washer connected from the pedal to the brake booster and master cylinder. Slide the brake light switch outboard along the brake pedal pin just far enough for the outer hole of the switch frame to clear the pin. Remove the switch by sliding it upward. Remove the black brake light switch bushing from the push rod.
- Loosen the brake booster retaining nuts at the pedal support and slide the pushrod and inner nylon washer (on vehicles without speed control) off the pedal pin.
- With the pedal support assembly removed, unfasten the locknut, followed by the pivot bolt, brake pedal, pivot spacer and bushing from the pedal support. Remove the speed control adapter if equipped, by unlatching the locking tab.
- With everything disassembled, clean all the parts and replace those that are worn. Pay particular attention to the bushings.
- Apply a light coat of engine oil to the bushings. Locate bushings and pivot spacer in brake pedal hub.
- Position brake pedal in the pedal support and install pivot bolt. Install locknut and tighten to 10-20 ft. lbs. (14-27 Nm).
- Install the inner nylon washer or speed control adapter, if equipped, and master cylinder pushrod, with the brake light switch bushing on the brake pedal pin. Position the brake light switch so that it straddles the push rod with the slot on the pedal pin and the switch outer frame hole just clearing the pin. Slide the switch down onto the pin and push rod. Slide the assembly down onto the pin and pushrod. Slide the assembly inboard toward the brake pedal arm. Install the outer nylon washer and push rod retainer. Lock retainer securely.
