1. With the ignition OFF and the brakes cool, apply the brakes 3 - 5 times or until the brake pedal becomes firm.

2. Install the CH-28662  Brake Pedal Effort Gauge (1) to the brake pedal (2) .

3. Measure and record the initial unapplied distance (a) from the brake pedal (2) to the rim of the steering wheel (3) . Note the points of measurement.

4. Apply and maintain a force of 445 N (100 lb)   to the brake pedal, as indicated on the CH-28662  gauge (1) .

5. While maintaining 445 N (100 lb)   of force to the brake pedal (2) , measure and record the distance (b) from the same point on the brake pedal (2) to the same point on the rim of the steering wheel (3) .
6. Release the brake pedal (2) and repeat steps 4 and 5 to obtain a second measurement. After obtaining a second measurement, proceed to step 7.
7. Average the first and second measurements recorded for the 2 applies of the brakes.
8. Subtract the initial unapplied distance (a) , from the average applied distance (b) to obtain the brake pedal travel measurement.
9. Compare the brake pedal travel measurement obtained with the specification. Brake System Specifications
