Brake Pedal Assy: Testing and Inspection

Test Procedure

1. With engine off and key at "OFF," pump service brake pedal until all reserve is exhausted from power booster. (A definite change in pedal feel will occur.)
2. Install special tool J 28662 onto brake pedal.
3. Hook end of tape measure over top edge of brake pedal and measure the distance to rim of steering wheel.
4. Apply service brake pedal with 445 N (100 lb.) force and remeasure.
5. Subtract the "at rest" measurement (Step 3) from the "applied" measurement (Step 4).

Interpreting Test Results

The difference between the two pedal positions is the pedal travel. The pedal travel should not exceed 57 mm (2.24 inches).

If pedal travel is greater than specification, refer to Brakes / System Diagnosis / Brake System Diagnosis.
