Stop lights stay on while driving.

Note: I am the original poster

My mechanic (another one from the mechanic who installed it) checked the installation. He is a Toyota Lexus mechanic, he said it is correct. I pointed out to him that, the brake lights stay on after I turn off the car.

I pointed out to him the attached photo. I see that there are threads on the nut bolt, by making an adjustment, it can release the brake pedal more towards up. I wonder if this can help.

The car brake lights in the back stays on when turned off. The warning lights come on only when I start drive.
Somehow, the car computer thinks that, while brake pedal is still being depressed (due to whatever problem it is) the gas pedal is also pushed simultaneously so the warning lights are coming on, IMO.

My mechanic also checked the wiring that goes to the stop light switch. He didn't see anything he says.

Been trying so hard to make this go away.

go to magicmechanic online and send him problem-hes a mastertech on any make and model

I had this same problem (brake lights won't come on when pushing on brake) I found that the brake light sending unit had come out of adjustment.Look under the dash by the brake pedal.There is a plastic threaded unit that needs to be pushed back towards the brake pedal lever.Careful not to push it to far or the brake lights will stay on. Hope this helps

Hi Chris....When you release the brake pedal, there is a switch underneath the brake pedal that disconnects the circuit to your brake lights causing your brake lights to switch off. Sometimes this brake light switch will go bad and need replacement. For the most part, replacing the brake light switch is very simple. Simply replace the brake light switch with a new one. If your brake light stays on after you turn your car off and you don't want to run your battery down, you may be able to get down underneath the brake pedal and manually pull up on the brake light switch to deactivate it until you can get it repaired. This method will only work if the brake light switch is just sticking.

I hope this helps FixYa!

Did you adjust the brake light switch correctly? To adjust the brake light switch, first press the brake pedal down a few inches, then pull the switch plunger rod out of the switch toward the brake pedal arm, as far as you can without using excessive force. Next, return the brake pedal to the pedal stop position against the pedal stop and pull the brake pedal toward the rear to push the brake light switch actuating plunger rod into the switch housing limited by the travel of the brake pedal arm rear travel stop position. This procedure automatically adjusts the brake light switch correctly.
If the brake lights still don't turn off with the brake pedal released, check the brake pedal arm for sticking or binding that is preventing the brake pedal arm from returning fully to the pedal stop when the brake is released.

mcdevito75 here, Are you sure your haedlite switch is off, if it"s on your brake lite will also stay on. However it could be the brake light switch out of adjustment. It"s located on the brake pedal, with your foot behind the brake pedal gently lift up on the brake pedal and see if the brake lights go out if they do or even if they don"t, have yoyr local shop check it out.

Brake lights- check your brake switch (stop lamp switch) usually right above the brake pedal if this gets knocked out or out of alignment the lights will come on just like you pushing down on the pedal.

Get under the dash ad look at your brake pedal lever. You will see a stop light switch that screww into a bracket with a 'button' sticking out of it. if pulling up on the brake pedal (even slightly) solves your problem, then the switch needs adjusting closer to the brake lever. If adjusting does not stop problem then replacement of brake light switch may be required.

look for loose wires near the brake pedal and linkage that may be grounding to it or moved when you hit he brake

look up under feet area brake peddal has a switch hooked to brake peddal could be bad switch or something catching it! good place to start!
