The brake lights on my 97cadillac de-elegence occasionally comes on while driving and only turns off after disconnecting the battery, I believe the switch or whatever it's called under the break pedal needs to be adjusted or replaced, but I'm no mechanic
Thank you

Hi there. You are probably correct in assuming that the brake switch under the pedal is either loose or faulty and is the source of the brake light issue. However, there are other sensors and connections that could also be triggering this warning light, so it would be best to first have a professional mobile mechanic come to your location and complete the brake light is on inspection. This will minimize mistakes in replacing or repairing the wrong component and ensure the right repairs are completed the first time.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
A red light that flashes on and off could signal low/almost empty brake fluid, but also a serious issue with the brake`s hydraulic system. If the light comes on and stays on, you could end up with a potentially catastrophic (and costly) brake failure.
If it remains lit after the parking brake is released or if it turns on and off intermittently while you`re driving, it means you need to add brake fluid. If you check the fluid, add as needed and the light still doesn`t turn off, you`ll need to have the brake system inspected.
If your brake lights are staying on, it will drain your battery. You need to disconnect your battery while the car is off or until you resolve this issue. The most likely cause for the brake lights staying on is the brake light switch sticking closed.
Brake light problems can include a socket whose connections are dirty or corroded or one whose wiring has become worn to the point where it`s only making an intermittent connection.
If your brake service warning light is always on, it could be due to a need for parking brake adjustment, worn brake pads, or hydraulic issues. If your brake service warning light turns on when you hit the pedal, it could be due to hydraulic loss on one side of your vehicle or low brake fluid in the master cylinder.
Emergency brakes vary by vehicle, but when a conventional lever or pedal E-brake is not released entirely, the brake warning light can come on. Some modern vehicles will beep if you are driving with the emergency brake engaged. To turn off the light, just fully release the E-brake.
Four Reasons Your Anti-lock Brake System Light Can Come On
The four common reasons that typically cause this light to turn on include a malfunctioning ABS module, low levels in the fluid reservoir, broken wheel speed sensors, or the system is turned off.
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.
Like all fuses, the brake light system fuse can be found in the power distribution center, which is under the dashboard or tucked away underneath the hood.

Okay so when I turn my lights on at night my brake lights do not work, when I don’t have my lights on they work fine.
ANSWER : Hi there. Based on your inquiry, it’s highly probable that you have a damaged light switch or some electrical fault inside the turn signal relay. However, it’s also possible that the brake switch above the brake pedal could also be the source of your problem. Due to the fact that multiple electrical components might be causing this issue, it’s a smart idea to first have a professional mobile mechanic complete a brake lights are not working inspection, so they can determine what’s causing all of these issues and recommend the right repairs.
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.

My ABS light and occasionally my emergency brake light is coming on and my brakes occasionally make a grinding noise when coming to a stop.
ANSWER : Hello there, many faults will cause your ABS light and emergency brake light to be seen on your 2009 Chevy Aveo5. When the ABS light is on it indicates there is a fault in the ABS system. This fault will leave a code stored in the ABS computer which when read will narrow down what is going on. Common faults are a wheel speed sensor, ABS module, or a wiring harness fault. To avoid any unnecessary repairs, a qualified technician such as one from YourMechanic will be able to diagnose your ABS light and make any repairs required to resolve the issue.
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.
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.
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.
