Toyota Corolla 4 door sedan. RE: Brake lights

The brake switch on brake pedal is bad. Tells transmission brake is depressed so it will come out of park. Also controls brake lights. It's a plunger type switch that just has a little pin that when extended completes a circuit and allows brake lights to come on. Shouldn't be hard to replace just might be aggravating to get to.

sounds like a vacume leak

good day, the one you filled maybe the reservoir of the clutch fluid, the one you should fill is the bigger tank for it is the one for brakes. hope this helps, have a nice day

Hello. I assume that you want to know the location of the switch that activates the brake light on the dash when the park brake lever is pulled. It is under the rear of the park brake handle; you need to remove the console to see it.

However...if your brake light in your dash is staying ON, I would first suggest that you look at the level of brake fluid in the master cylinder reservoir. If it is low, the light will come on, also. The fluid level in the master cylinder drops proportionally as the brake wear. I would bet that your fluid is low; about an ounce of fluid decrease will light up the brake light.

Check the park brake position sensor switch.
The sensor switch or the parkbrake actuating lever position may be mal-adjusted.

The positive or hot return wire for the brake light switch is now grounding out,brake light switch is now faulty or a short in the wiring is present bring the car to an auto electrician for diagnosis

The brake light switch is on your brake pedal.You may have more then one switch on the pedal.

The switch is located above the brake pedal, about six inches. Sometimes there is a rubber stopper attached to the brake pedal assembly that closes the switch. If it is missing, nothing pushes the switch. Put a small bolt through the hole with a nut.

on the brake pedal, there is a little switch, up under the dash, that controls the lights, replace that switch

Locate the brake switch up above the brake pedal. Push in on plunger and check if brake lights go out. This switch can be unplugged and removed from its spot at the pedal. Then you can pull out plunger and reset it, put back in its spot, and let pedal readjust to the appropriate travel. It should automatically set to correct stroke length after pulling plunger outward to its furthest length. If this switch, or its adjustment is not to blame, post again. I will help more if needed.

Thanks, I hope this helps. TT
