Brake Pedal Excessive Travel

1. With the engine off and key off, pump the service brake pedal until all the reserve vacuum is exhausted from the brake booster. A definite change in pedal feel will occur.
2. Install the SA9304NE brake pedal effort gage or equivalent, onto the brake pedal.
3. Hook the end of the tape measure over the top edge of the brake pedal and measure the distance to the rim of the steering wheel.
4. Apply the service brake pedal with 445 N (100 lb) force and re-measure. The difference between the "at rest" pedal position and the "applied" pedal position is the actual pedal travel and should not exceed 57.0 mm (2.25 in).
5. If the pedal travel is greater than the specification, refer to Brakes Complaint/Condition Chart for possible causes.
