Brake Light Switch

If you've replaced all your brake light bulbs but still don't have brake lights, chances are you've got a bad brake switch. There are two brake switches on the brake pedal of your 850/70. One switch has a vacuum line attached, this is for cruise control while the other switch (the larger of the two) is for powering the brakes lights. The internal contacts tend to burn out over time and simply replacing the switch is typically all that is necessary to bring your brake lights back on. Of course don't forget to check the basics like fuses and bulbs! You'll need a Torx 25 driver to remove the lower bolster cover to access the brake switch. See the tool section of our website for our torx driver tools.
