Brake Pedal Travel Measurement & Inspection
WARNING: This page is about a different car, the 2002 Pontiac Grand Prix and 2002 Oldsmobile Intrigue. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Special tools required: Brake Pedal Effort Gauge (J-28662).
- 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 brake pedal effort gauge to the brake pedal.
- Measure and record the distance from the brake pedal to the rim of the steering wheel. Note the points of measurement.
- Apply and maintain the brakes with 100 Lbs of force to the brake pedal, as indicated on the brake pedal effort gauge.
- While maintaining 100 Lbs of force to the brake pedal, measure and record the distance 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 next step.
- Average the first and second measurements recorded during the 2 applies of the brakes.
- Subtract the initial unapplied measurement, from the averaged, applied measurement to obtain the brake pedal travel distance. See BRAKE PEDAL TRAVEL table. Maximum brake pedal travel should be measured with the ignition off, brake booster power assist depleted, and the brakes cool.
