J 28662 Brake Pedal
Effort Gauge
Diagnostic Procedure
At frequent intervals, check the brake pedal travel. Brake pedal travel
is the distance the pedal moves toward the floor from a fully released position.
Make this check with the brakes cold. Apply about 445 N (100 lb)
on the pedal using the J 28662
.
- Apply the brake pedal six to ten times with the engine OFF.
- Measure the distance
(1) from the bottom of the steering wheel to the brake.
- Apply about 445 N
(100 lb) of force to the brake pedal using the J 28662
.
- With the force applied to the brake pedal, measure the distance
(2) from the bottom of the steering wheel to the brake pedal.
- Subtract measurement (1) from measurement (2) in order to determine
brake pedal travel.
- Brake pedal travel should be 50-72 mm (2-3 in).
- If brake pedal travel exceeds specifications, refer to
Brake System Diagnosis
