Brake Pedal Travel Measurement & Inspection
WARNING: This page is about a different car, the 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Required Tools: Brake Pedal Effort Gage (J-28662).
- 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 the Brake Pedal Effort Gage 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 (445 N) of force to the brake pedal, as indicated on the Brake Pedal Effort Gage.
- While maintaining 100 lbs (445 N) 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. See Fig 1 . Release the brakes and repeat to obtain a second measurement.
- Average the first and second measurements recorded during the 2 applies of the brakes. Subtract the initial measurement, un-applied, from the averaged, applied measurement to obtain the brake pedal travel distance. Maximum brake pedal travel-measured with the ignition OFF, brake booster power assist depleted, and the brakes cool is 2.24 in (57 mm).
