Brake Pedal Assy: Service and Repair
Brake Pedal and Bracket
Removal and Installation
NOTICE: Do not service the brake pedal without first removing the stoplamp switch. Remove this switch with the brake pedal in the at-rest position. The switch plunger must be compressed for the switch to rotate in the bracket. Attempting to remove the switch when the plunger is extended (during pedal apply) results in damage to the switch.
NOTICE: The holes on the brake pedal bracket for the bottom booster studs are slotted, the holes for the top studs are not. If the brake booster is not pulled forward far enough for the bracket to clear the studs, damage to the bracket can occur.
NOTICE: Do not press, pull or otherwise move the brake pedal while installing the stoplamp switch. Install this switch with the booster push rod attached to the brake pedal and with the brake pedal in the at-rest position. Installing this switch with the brake pedal in any other position results in incorrect adjustment and damages the switch.
NOTICE: The brake booster check valve must be disconnected from the brake booster prior to removing the master cylinder or the master cylinder seal may be drawn into the brake booster.
