  Q: What are Brake Light Switches, and How to locate, remove, and adjust them on Volvo V40?

  A:

  The stop light switch is provided on the pedal bracket behind the facia, models with cruise control have two switches on the brake pedal, the upper one is the stop light switch, and no vacuum pipe is connected. To remove it, undo the retaining screws, which the lower screw is behind a trim cap, and remove the driver's side lower panel from the facia with the wiring connector from the footwell light. After removing the wiring connector, unscrew the switch and remove it from the bracket. For refitting and for adjustment, gently push the switch in position in the pedal mounting bracket. Use a continuity tester across the switch terminals screwing the switch in until you get an open circuit and check it gently depress the pedal to check continuity after about 5 or so mm of travel. Adjust the switch accordingly to achieve proper operation because the anti-lock braking system performance may be impacted due to incorrect adjustment. If a continuity tester is not available, the adjustment can be checked by reconnecting the switch and having an assistant watch the stop-lights with the ignition switched on. After correctly adjusting the stop-light switch, attach the wiring connector and refit the panel to the facia making sure the switch for stop-lights works properly before using the vehicle.
