To adjust the brake pedal released height, begin by peeling back the carpet and insulator pad, and for models from 2004 onward, disengage the cruise control and stoplight switches by turning them 45 degrees counterclockwise. With the brake pedal fully released, measure the distance from the top of the pad to the floor. If the height is incorrect, loosen the locknut in front of the power brake booster clevis and turn the input rod until the correct height is achieved, then tighten the locknut. After adjusting the pedal height, check the freeplay by pressing down lightly on the brake pedal and measuring the distance it moves freely before resistance is felt; this should be within specified limits, and if not, loosen the locknut for the brake booster clevis and adjust the input rod accordingly before tightening the locknut again. Following the adjustments, check the pedal depressed height by pressing the brake pedal fully with the engine running and measuring the pedal pad-to-floor distance. If the minimum depressed height is below specifications, for models from 2004 onward, press the stoplight and cruise control switches inward until their threaded ends contact the pedal, then turn them 45 degrees clockwise to secure them in position.
