Brake Pedal Height & Free Play

Measure pedal height from floor board to face of pedal pad. See BRAKE PEDAL HEIGHT & FREE PLAY SPECIFICATIONS table for specification. If pedal height is incorrect, go to next step.
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. (26 N.m). Install stoplight switch until it lightly contacts brake pedal stopper in rest position. Turn switch back one turn and measure clearance between stoplight switch threaded shaft and brake pedal stopper.
Clearance is .06-.10" (1.5-2.5 mm). Ensure stoplights work properly.
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 table.

NOTE: If clearance between stoplight switch threaded shaft and brake pedal stopper is correct, brake pedal free play should be correct. If brake pedal free play is still not correct, there is another problem in the brake system.
