Brake Pedal Assy: Adjustments

1. With engine running and brake pedal in rest position, measure distance between face of pedal and floor mat.
2. If distance is not 5.79-6.18 inches, adjust pedal height as follows:
a. Remove left lower instrument panel trim section and air duct.
b. Loosen stop lamp switch sufficiently to gain clearance for pedal adjustment.
c. Loosen locknut and rotate pedal pushrod as needed to obtain specified pedal height, then tighten locknut.
d. Adjust position of brake light switch so that plunger lightly contacts pedal stopper and brake lamps are off when pedal is released.
e. Check pedal free travel.
3. With engine stopped, depress brake pedal several times to ensure there is no vacuum pressure in booster.
4. Release pedal, then press pedal down until the beginning of resistance is felt, measuring the pedal travel. Pedal free travel is the amount that the brake booster air valve is moved by the pedal pushrod.
5. If pedal travel is not .12-.24 inch, adjust pedal freeplay as follows:
a. Adjust pedal free travel by loosening locknut and rotating pedal pushrod.
b. Ensure brake lamp switch and pedal height are properly adjusted, then start engine and confirm that free travel still exists.
c. Check pedal reserve distance.
6. Release parking brake, then start engine.
7. Depress brake pedal, then measure distance from face of pedal to floor mat. If pedal reserve distance is not more than 2.56 inch with an applied force of 110.2 lbs., check and repair brake system as needed.
