- With the ignition OFF and the brakes cool, apply the brakes 3-5 times,
or until the brake pedal effort increases significantly, in order to deplete
the brake booster power reserve.
- Install theJ 28662
to the brake pedal.

distance (1) from the brake pedal to the rim of the steering wheel;
note the points of measurement.
- Apply and maintain the brakes with 310 N (70 lb)
of force to the brake pedal, as indicated on the J 28662

- 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.
