Brake Pedal Height & Free Play
- Measure pedal height from floor board to face of pedal pad. See BRAKE PEDAL HEIGHT & FREE PLAY SPECIFICATIONS . If pedal height is incorrect, go to next step.
- On ES300, LS400 and RX300, remove undercover panel, lower pad and air duct. On all models, disconnect stoplight switch connector. Loosen stoplight switch lock nut, and remove stoplight switch. 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 19 ft. lbs. (25 N.m).
- Install brake light switch. On ES300, LS400 and RX300, install undercover panel, lower pad and air duct.
- STOP engine and 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 pedal free play. Ensure pedal free play is as specified. See BRAKE PEDAL HEIGHT & FREE PLAY SPECIFICATIONS .
NOTE:
If clearance between stoplight switch threaded shaft and brake pedal stopper is incorrect, correct brake pedal free play. If brake pedal free play is still not correct, another problem exists in brake system.
