It turns the rear brake lights on as a safety feature. The brake pedal is pushed in, causing the fluid to move forward in the brake cylinder,activating a brake light switch. Even if the vehicle is off, the lights will still come on.
A dashboard light appearing when brake pedal is depressed usually means brake fluid is low.
It is the distance between floorboard and pedal top, when the brake pedal is fully depressed (after applying brakes).
check the brake pedal, there is a switch on the back of the pedal that depressed when the brake is depressed that turns the lights on, when this is loose it keeps the lights on.
Check rear bulbs, rear brake bulb fuse, and check the swith on the brake pedal.
Brake lights are on continuously while you are driving. Every time the brake pedal is depressed.

It is because the brake light switch under the brake pedal is faulty. usually replacing this will solve the problem. it is designed in such a way that when the brake pedal is depressed the switch completes a circuit and the lights come on. the fault occurs when the switch closes the circuit even though the pedal is not depressed. hope this helps.
Possibly the brake light switch at the brake pedal has stayed depressed or stuck.
The brake pedal has a hinge or pivot pin, give it a shot of lubricant,should stop squeaking.
If both brake light bulbs fail to come on when the brake is depressed I'd check first to see if there may be a fuse that controls the brake light circuit. If there is no fuse and/or the fuse appears to be okay, the most likely culprit is a faulty brake light switch. This switch is located up and behind the brake pedal. There is a plunger that moves in and out acting as a switch when the brake pedal is depressed. It is this switch which possibly may be the culprit.
The brake pedal electrical switch can be found below the dashboard in the passenger compartment. The switch will be on the drivers side of the dashboard.
Check the brake switch under your pedal (which needs to be pushed when the brake pedal is depressed). This is what the problem was on my friends Sentra. As long as you have checked the lights and fuses, this should do it.
Shifter is blocked by a device attached to the brake pedal. If the brake pedal is not depressed it wont allow you to change out of park. There should also be a bypass button next to the shifter, in case the cable to the pedal breaks.
THE BRAKE LIGHT IS LOCATED BELOW THE DASH. LOCATE THE ARM HOLDING THE BRAKE PEDAL AND YOU WILL SEE A SWITCH THAT COMES OUT WHEN THE PEDAL IS DEPRESSED TURNING THE LIGHT ON. WHEN THE BRAKE IS RELEASED THE SWITCH DEPRESSES AGAIN TURNING THE LIGHT OFF.
Brake system has air in it.
Take your toe and pick UP on the brake pedal. The brake pedal may not be returning as it should.
Check to make sure you have power at the brake light switch, if you have power at the switch, depress the brake pedal, and check for power out of the switch, if no power out with the brake pedal depressed, you need a new brake pedal switch.
Then fix them. Start by checking the bulbs - those are dual filament bulbs, and it's possible that the filament for the brake lights was compromised. If those check out, see if you have power to the brake light circuit with the brake pedal depressed by using a test light. If you don't have power, what I'd do next is find the relay and test that. Remove the relay, check for power at the 30 post - it should be hot constantly. Then check for power at the 86 post with the brake pedal depressed. If you have power at the 86 pole with the brake pedal depressed and at the 30 pole, then the problem is either the relay itself, or the wiring along the 87 circuit. If you don't have power at the 30 pole, check to see if there's a fuse specifically for the brake lights. If you don't have power at the 86 pole with the brake pedal depressed, the problem is somewhere between the brake pedal and the relay. I'd start with the brake light switch itself if that were the case. Should be located at the top of the brake pedal.
The master cylinder seals are worn out. Have it replaced soon, very soon!
Brake Light Failure to Turn OffThe most common cause for brake lights to remain ON when the pedal is not depressed as that the brake light switch is not properly adjusted.IF the brake light switch is definitely good [working properly] then the most likely cause for the brake lights to remain turned on is that the position of the switch [the distance of the plunger tip from the brake pedal arm] is not adjusted properly.Most mechanical type switches are adjusted by screwing the switch [which has a threaded mounting to a hole in the mounting bracket] either toward or away from the brake pedal arm [which depresses the switch plunger to turn off the brake lights].It is immeasurably helpful to have an assistant stand behind the vehicle to observe and report the changes [on-off, etc.] as you make adjustments of the switch position. You should continue to make changes in the adjustment until the brake lights stay OFF when the brake pedal is not depressed, and the brake lights come on when the pedal is depressed.
follow the brake pedal under the dash , on top of the pedal will be a 2 wire switch that opens when the pedal is depressed. yes its wired in the harness The top of the brake pedal has a hard-rubber covering on it. Is this switch under this cover?
Check your brake light switch located above the brake pedal. Check to make sure that the brake pedal rests against the switch. When the brake pedal is depressed than the lights should turn on, but when you let go of it, it should return up and meet with the switch.
open the drivers door neal down,look at the brake pedal and follow it up. There will be a switch that pushes in and out as the brake pedal is depressed and let go.
there is an electrical switch called a brake sending unit attached to the brake pedal under the dash check that there is an electrical switch called a brake sending unit atatched to the brake pedal under the dash check that
