Tools Required

1. With the engine off and the key at OFF pump the service brake pedal. Pump until all of the reserve is exhausted from the power booster. (A definite change in pedal feel will occur.)
2. Install the J 28662 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.
5. Subtract the at rest measurement from step 3 from the applied measurement in step 4. The difference between the two pedal positions is the pedal travel. The pedal travel should not exceed 57 mm (2.24 in).

If the pedal travel is greater than specification, refer to the Brake System Diagnosis table.
