Brake Light Switch: Service and Repair

REMOVAL

Fig. 3 Stop light switch replacement:

1. Disconnect the wire harness at the connector from the Brake Pedal Position (BPP) switch.

NOTE: Locking tab on connector must be lifted before connector can be removed.







2. Remove the hairpin retainer and slide the BPP switch, the push rod and the nylon washers and bushing away from the brake pedal. Remove the BPP switch by sliding the BPP switch up/down as required to remove.

NOTE: Since the BPP switch side plate nearest the brake pedal is slotted, it is not necessary to remove the brake master cylinder push rod and one spacer washer from the brake pedal pin.

INSTALLATION
1. Position BPP switch so that the U-shaped side is nearest the brake pedal and directly over or under the pin. Then slide BPP switch down or up trapping the master cylinder push rod and black bushing between the stoplight switch side plates. Push BPP switch and push rod assembly firmly toward brake pedal arm. Assemble outside white plastic washer to pin and install hairpin retainer to trap whole assembly.

CAUTION: Do not substitute other types of pin retainers. Replace only with a production hairpin retainer. Component damage may occur.

2. Assemble the wire harness connector to the BPP switch.

NOTE: BPP switch wire harness must have sufficient length to travel with BPP switch during full stroke of brake pedal. If wire length is insufficient, reroute harness or replace as required.

3. Check BPP switch for proper operation.
