Loosen brake pedal-to-power brake unit push rod lock nut. Adjust pedal height by turning brake pedal push rod. Tighten push rod lock nut to specification. See TORQUE SPECIFICATIONS .
- Install stop light switch and connect brake light switch wiring harness connector. Push in brake pedal .2-.39 in. (5-10 mm) and turn stop light switch to lock the nut in position where brake light goes off. After installation, push in brake pedal .2-.39 in. (5-10 mm) and check that brake light illuminates.
- Turn ignition off. Depress brake pedal several times until power brake unit is depleted. Push brake pedal by hand until a second point of resistance is felt, then measure the difference. Ensure pedal free play is as specified. See BRAKE PEDAL HEIGHT & FREE PLAY SPECIFICATIONS table.
- If incorrect, check stop light switch clearance. See STOP LIGHT SWITCH CLEARANCE table. If clearance is OK, trouble shoot brake system. Install instrument panel components as necessary.
