- Install theJ 28662 to the brake pedal. See Special Tools and Equipment .

- Apply and maintain the brakes with 310 N (70 lb) of force to the brake pedal, as indicated on the J 28662 . See Special Tools and Equipment .
- While maintaining 310 N (70 lb) of force to the brake pedal, measure and record the distance (2) from the same point on the brake pedal to the same point on the rim of the steering wheel.
- Release the brakes and repeat steps 4 and 5 to obtain a second measurement. After obtaining a second measurement, proceed to step 7.
- Average the first and second measurements recorded during the two applies of the brakes.
- Subtract the initial measurement, unapplied (1), from the averaged, applied measurement (2) to obtain the brake pedal travel distance.
Specification: Maximum brake pedal travel - measured with the ignition OFF, brake booster power assist depleted, and the brakes cool: 70 mm (2.75 in).
