With the brake pedal fully released, measure the distance from the top of the pad to the floor with the carpet and padding removed, ensuring the measurement is taken at a right angle to the floor. Release the brake light and cruise control cancel switches by turning them counterclockwise 45 degrees. Loosen the lock nut just in front of the power brake booster clevis, then turn the booster input rod until the pedal height is correct. After achieving the correct height, tighten the lock nut. With the threaded portion of the brake light and cruise control cancel switches contacting the bracket, turn the switches 45 degrees clockwise to lock them in place, and adjust the brake light and cruise control switches if necessary.
