Service Procedure
Inspection Procedure1. Remove the insulator panel on left side.
2. Inspect for the presence of the brake rod retaining clip and orientation of the brake pedal bushing.
^ If the clip is present and the bushing retaining flange is on the retaining clip side of the brake pedal pushrod (refer to illustration), only the retaining clip requires replacement.
- If the clip is present and the bushing retaining flange is on the side opposite of the retaining clip, the bushing between the brake pedal and the activation rod, the retaining clip, and the brake pedal position sensor must be replaced. Proceed to Brake Bushing Replacement Procedure.
- If the clip is missing, the brake pedal assembly, retaining clip, and the brake pedal position sensor must be replaced. Proceed to the Brake Pedal Assembly Replacement Procedure (very few vehicles will require brake pedal assembly replacement).
