- With the ignition OFF and the brakes cool, apply the brakes 3-5 times, or until the brake pedal becomes firm, in order to deplete the brake booster power reserve.
- Install the J 28662 to the brake pedal. See Special Tools and Equipment .
- Measure and record the distance (1) from the brake pedal to the rim of the steering wheel. Note the points of measurement.
- Apply and maintain the brakes with 490 N (110 lb) of force to the brake pedal, as indicated on the J 28662 . See Special Tools and Equipment .
- While maintaining 490 N (110 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 2 applies of the brakes.
- Subtract the initial measurement, unapplied (1), from the averaged, applied measurement (2) to obtain the brake pedal travel distance.
Specification: The maximum brake pedal travel, measured with the ignition OFF, the brake booster power assist depleted, and the brakes cool is 76 mm (2.987 in).
