Experienced mechanics share their insights in answering this question :
Sometimes a faulty brake switch can cause this issue to occur. The brake switch is located behind the brake pedal and sends an electrical signal to activate ABS sensors and rear brake lights. If the switch is faulty, it can cause inconsistent operation of the brake lights. A faulty ground wire or exposed wire to the brake lights or electrical relay can also cause this problem.

Bad Switch: One common reason for the Parking Brake light to stay on is a failing or failed switch. This can be checked easily by jiggling the handle after it is down. If the light turns off (or turns off and then back on), the switch is the most likely culprit and will need to be replaced.
Why is the brake light on while driving? When your brake light comes on, your car is letting you know that either your vehicle is low on brake fluid, the emergency brake is activated, there`s trouble within the ABS unit, or there`s a problem with the sensors.
If you`re wondering “why does my brake light come on and off?” It could be because the sensors are defective. There are quite a few sensors that work with the braking system and they could be coming on and off because of an electrical malfunction.
If both lights are turned on, that means your brakes are not working. You should pull over immediately and stop the car. Brake System: This light turns on if your parking brake is engaged while you`re driving. It could also mean that your brake fluid is low.
The brake light is controlled by a switch on the linkage —- there is no computer involved, you simply adjust the switch position to contact the linkage. thereby turning off the light. For the master cylinder you fill the reservoir with fluid.
A stopper is a plastic/rubber part that goes into the brake pedal of your car. This helps to push the brake light switch to the off position while you`re not braking. These stoppers can wear off due to age, making the switch stay in on position and the lights illuminate. Replacing the stopper can fix the issue.
The most common reasons your brake light is on: The Parking Brake is engaged. Brake Fluid is low or leaking. Worn brake pads.
Driving with the Brake Warning Light on should not be done as this is dangerous. It means your brakes are not working properly and need to be repaired as soon as possible.
If a sensor goes bad, then you may experience wheel lock or notice that there is low fluid in the reservoir. The anti-lock brake system fluid level sensor monitors the level of the brake fluid in the reservoir in order to inform the driver if the level falls below the minimum safe level in the event of a malfunction.
If both the ABS and the brake system light come on at the same time, your vehicle is no longer safe to drive. This means there is a serious problem with the car`s braking system and continuing to drive puts yourself and others at risk.
Ford F150 ABS Light – ABS module problems. Failure of a Ford F150 ABS pump and module will result in a variety of illuminated warning lights being displayed on your dashboard. Other lights such as the traction control, ESP, and brake lights, often signal further ABS module problems.
ABS light and brake light illumination may be as simple as low brake fluid level in the reservoir which may be normal brake pad/brake shoe wear or a sign of a brake fluid leak which should be investigated. Check the fluid level first and top up if required. See if the lights go off.
Tip: When your brake lights stay on while your car is stopped, it can drain your battery. It`s important to resolve brake light issues right away so as to not drain your battery.

When I put my foot on the brake my back left brake light goes off, when I take it off the brake the brake light comes on
ANSWER : I would suggest trying to disconnect and reconnect the wiring to the rear lights. I have seen these older Toyota vehicles rear lighting short out on the lights themselves due to the way the light circuit was made on the lamp housing. Look at the housing circuit on the light to see if one is touching another, and that could tell you why it is malfunctioning. There could also be a problem with the brake light switch. If you are not comfortable dealing with wires, I recommend getting in touch with a certified mechanic who can look at your brake light issue for you to see what’s going on.
EPC light on 2004 Jetta. Code said brake switch faulty, but brakes lights worked. Replaced brake switch, now no brake lights.
ANSWER : Hi there. The first thing that pops in my mind beyond of what you have listed is perhaps the electrical harness attached to the brake switch. Perhaps the harness itself is damaged or you have an exposed wire, loose ground wire somewhere. You might want to have a professional mobile mechanic come to your location and complete a brake lights not working inspection to help you diagnose this issue.
Brake lights are not working. replaced brake light swtch still no brake lights. the third brake light the connection was melted at
ANSWER : The first thing to do is to repair third brake light and replace the brake light fuse and then see if the third brake lights work and the lower lights start working? If only the 3rd brake light starts working then you may need a further checks on the turn signal flasher or switch could be bad.
Battery light goes on when I start car then turns off, if I rev engine light comes back until rpms go down. Abs goes comes on/off
ANSWER : Batteries can die due to faults in the charging system so ideally a suspected "faulty" battery should be load tested before a decision is made to condemn it. The only exception to this rule is if the battery is already clearly "old" (greater than 5 years) but even then once you put a new battery in, as a replacement for a "dead" battery, you have to comprehensively check out the charging system. Diagnostic Trouble Code P0460 will result in disruption of the dashboard fuel gauge’s ability to accurately report your tank’s fuel levels. The fuel gauge readings may be erratic, or read somewhere off scale. Vehicles equipped with a low fuel warning light feature may also suffer from erratic low fuel warnings in the event of a code P0460. Unless the P0460 code has been reported alongside other trouble code, all of the vehicle’s essential systems should otherwise function normally. I would recommend that you request a check engine light diagnostic to first resolve the fault causing the P0460 code to set. The check gas cap light warning light could be due a faulty gas cap and/or small leaks in the EVAP system.
I replaced the brake light switch. Gear lever unlocked because it had locked. Now the brakes feel hard.
ANSWER : Hi, thanks for writing in. You need to check the brake switch install adjustment. You may have the switch adjusted too tight and it is holding the the brake pedal partly down. This will cause the brake master cylinder to not release the brakes when you let off the pedal. Readjust the switch away from the pedal until you feel some free play again in the pedal. This should fix the problem. If you would like help, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose this issue for you, and make or suggest any repairs as needed.
My brake lights and dash brake light come on while driving.
ANSWER : These types of warning lights will generally store a fault code in one or more of the vehicles control modules. The warning lights you are getting may be the result of a faulted brake pedal position sensor or wheel speed sensors. Further diagnosis will be necessary to determine the exact cause. Consider hiring an experienced technician like one from YourMechanic who can come out for a closer look and offer a more personal diagnosis of your warning lights.
Brake sensor is to sensitive causing brakes to flicker while driving. 2005 Mercury Montego
ANSWER : Hi there – your brake light switch needs a minor adjustment. It is adjusted too "tight" or close to the brake pedal lever, or possibly has failed. Adjusting/replacing it will eliminate this flickering problem. I recommend a brake light isn’t working inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
