J 28662 Brake Pedal Effort Gauge
Check the brake pedal travel at frequent intervals. Brake pedal travel is the distance the brake pedal moves toward the floor from a fully released
position. Make this check with the brakes cold and with tool J 28662.
1. With the engine off, press and release the brake pedal. Do this five times in order to exhaust vacuum from the vacuum booster.
2. Wheel to the brake pedal with the brake pedal released.
3. Apply about 455 Nm (100 lbs) on the brake pedal. Use the J 28662.
4. Measure the distance again.
5. Subtract the first measurement from the second measurement.
6. If the brake pedal travel is more than 42 mm (1.7 inch), refer to Brake Pedal Replacement.
