The brake light switch is located on a bracket at the top of the brake pedal; loosen the locknut and unscrew the switch from its bracket. Disconnect the wiring harness at the brake light switch, then loosen the locknut and unscrew the switch from the pedal bracket. Installation is the reverse of removal. Check and, if necessary, adjust the brake pedal height. Loosen the switch locknut, adjust the switch so that the plunger protrusion is within the specified range, and then tighten the locknut. Plug the electrical connector into the switch, ensuring the brake lights illuminate when the brake pedal is depressed and turn off when released; if not, repeat the adjustment procedure until the brake lights function properly. Check and, if necessary, adjust the brake pedal freeplay.
