Brake Light Switch Replacement Service

What is the brake light switch and how does it work?

The brake light switch is a mechanical switch activated when you press the brake pedal. The switch has a plunger in it that contacts a lever in the brake pedal assembly. As that plunger is depressed when you push on the brake pedal, the contacts in the brake light switch closed and voltage flows to the brake lights — turning them on. The brake light switch is also in the circuit that controls the cruise control disengagement and the shift interlock safety feature installed on all newer cars. Failure of the brake light switch occurs due to wear on the internal electrical contacts in the switch, poor switch terminal connections, maladjustment of the switch, or damage to the brake pedal assembly.

When to consider replacing the brake light switch?

  • No brake lights. If depressing the brake pedal does not cause any of the brake lights to illuminate, the continuity of the switch will be tested. If only one brake light is out, then the issue is not the switch but rather the bulb, bulb socket or brake light circuit integrity.
  • Unable to shift out of park. The brake light switch is also wired into the shift interlock mechanism. If you are unable to shift out of park, with your foot on the brake, check to see if the brake lights will illuminate as you push the pedal. If they do not illuminate, failure of the brake light switch may be the cause of the no shift.
  • Intermittent operation of the brake lights or late operation. The brake light switch has to be in the proper position, and work consistently if the brake lights are to come on the instant you press the brake pedal. The switch can sometimes require adjustment, or the contacts may degrade, causing inconsistent operation of the switch.

How do mechanics replace the brake light switch?

  • The switch is first tested using a multimeter, including the terminal contacts to the switch, to determine if it is faulty. If the switch is functioning, the entire circuit must be tested to determine the cause of no brake lights.
  • Should the switch be judged defective, the switch is unthreaded from the mounting boss near the brake pedal assembly.
  • The new switch is threaded in and locked with an appropriate locknut once the new switch is properly adjusted.
  • The operation of the switch is tested to ensure instant illumination of the brake lights upon pressing the brake pedal.

Is it safe to drive with a brake light switch problem?

No. Should the brake light switch have failed, it is unsafe to drive the vehicle because drivers behind you will have no indication that you are slowing, intend to slow, or are stopped. Always address a failure of this type promptly to ensure your safety while driving.

When replacing the brake light switch keep in mind:

  • The mechanic will test the brake light switch directly to ensure that the issue is not elsewhere in the brake light circuit.
  • Occasionally, the issue is a maladjusted switch or a loose contact, and the mechanic can resolve the problem without switch replacement.

Audi A4 - Car is making a noise - Los Angeles, California
Today, David came in and did an inspection on my dying audi a4. I've have been to many other mechanics that I personally known, but they all failed to give me the correct inspection and the conclusions. When David arrived, he was friendly, professional, caring, and dedicated. after the very quick but I must say, VERY thorough inspection, he insisted to drive a long ways taking time of of his personal schedule to come to the dealer that sold me this car to confront them about the smog issues. all throughout the process, I must say that not only did i get more information than I ever though I could receive, but I've also made a connection and most importantly, a friend. I do not write reviews hardly ever, but you would honestly had to be a mad man to not write a review on such a mechanic that literally pours out his heart to your car and to you personally. I HIGHLY recommend this mechanic! thank you David Martin!

Audi A4 - Coolant is leaking - Tampa, Florida
Chris arrived early and was very professional and knowledge. He made the diagnosis quickly, and in fact was able to diagnose both my cars in the time allotted for one. Parts had to be ordered, so I haven't had the repair yet. But Im confident in his abilities and look forward to getting it done.

Audi A4 - Pre-purchase Car Inspection - Atlanta, Georgia
Christopher arrived early for my appointment, even with Atlanta traffic. He was very conscientious of what I wanted to accomplish with his visit, which was to address any issues with my car, so that I could have the seller to work on those things. He was friendly, knowledgeable and went above and beyond the call of duty. He comes highly recommended!

Audi A4 - Pre-purchase Car Inspection - Venice, California
Ricardo was an absolute pleasure to spend the morning with and he helped me secure my next car! He was extremely knowledgeable and gave me tips on how to check for suspension problems and how-to spot an oil leak before it takes place. 10/10 would recommend! thank you and I look forward to having you help me in the future.
