Thank you for this video. Today I get in my car and I notice my brake light on dash stays on. I looked at your video and discovered why. I just put brake fluid (Dot 3) in my car and the light went right out. Thank you soo much. This vid saved me a trip to my mechanic.
thank you for this video, very informative and it helped. I had checked the fluid and it was at the minimum mark, I figured it was still enough, but I think it was borderline. again, thanks for this video, saved me from looking like a moron at the brake shop.
I did the "hard" checks first. Checked ABS codes, checked tire pressure (reset switch), monitored Wheel speeds. Didn't think to check fluid. Added fluid, light went off. Thanks for reminding me to look for the simple things first!
Thank you! My brake light stayed on after I replaced my rear rotors. Everything worked fine but it wouldn't go off. Your level sensor plug tip was right. Even Wagner Brake's video didn't mention it as a possible cause but you did!
Good suggestions about getting the codes checked and such, however, as a rule of thumb, it may not be a good decision to put brake fluid in a brake reservoir if the brake fluid level is low for several reasons: 1. The brake reservoir is a good indicator of brake pad condition. If your brakes are low, it could be that your pads are low. As the Caliper piston pushes the brake pad against rotors that causes the vehicle to stop moves further out due to wear of the brake pads, brake fluid takes up the lost space, therefore, when the pads are replaced and the piston is pushed back into its original position, the brake fluid level goes back to its original full level. In addition, when the brakes are repaired, the fluid will overflow once the caliper piston is pushed back to its original position. The light might be on due to pads being too low. Some vehicles have brake pad level sensors that warn if the brake pads are too low. 2. There might be a leak in the brake lines that will require repair. Low brake pressure can make the light come on. In this case, if you are away from home and see a puddle, it might be a good idea to put fluid in to get you safely home or to a repair shop. Not a good idea to prolong as the issue can get progressively worse and the brakes can fail. Nevertheless, if there is no leak, I don't suggest putting brake fluid in the reservoir as brake fluid do not evaporate because it is a sealed unit that is not water based.
Thanks! I was worried I'd have to take it in to the shop, which is not a fun experience because the guys there keep telling me I have issues that I don't have. I was once told I needed to replace all of my tires, despite two of them only being a year old.
BIG help! Thanks man! I am a woman and I was worried that I may go to the shop again, but thanks to your clear video I just fixed the light on my dashboard by doing this... Also, I've removed the battery to reset the car...
If your brake fluid level is at minimum, you probably have a fluid leak, somewhere. There can be no other reason for the reservoir to have lost fluid. Leaks can occur anywhere in the system, but mostly at the wheel cylinders.
If your brake fluid is low it means your pads are low and the pistons in the calipers are all the way out and that where the fluid went or you have a leak somewhere
It kind of worked on my silverado 2003. My truck had intermittent emergency tones, it turned on and off and gave me a big headache. I looked under the hood reconnected a lose wire connector near the brake booster just like you told me to. (even though it wasn't the exact wire to the reservoir like you demonstrated) Now the tone went away (thank god) but the red light is still on and concerning. I hope I goes away soon by it self maybe it takes a few miles to turn off. Maybe I'll disconnect the negative battery terminal to rest it see if that works.
Great video mate. I am the first to watch the video! Thumbs up. I thing the other reason for brake light may be the switch/ wiring problem with hand brake lever. thanks for video. Regards,
LearningZone If the Emergency Brake is even on a wee bit the light will come on, ive ran into that a few times actually and it can stump people! I just made an annotation in the Video after I read your comment, thanks for watching!
I have a 2005 escalade ext. Brake light came on bc a line ruptured and I lost fluid. My dash says service brake system and stability sys disabled. I replaced all the brake lines, bled the lines, and topped off my master cylinder reservoir. Everything seems to be good now but my brake light on my dash is still on. My abs light is not on. Only my brake light and my TC light. Do I have to get these lights turned off or will they eventually reset themselves since I have fixed the problem? It's been 2 days now and brake light and TC light are still illuminated
Is there a sensor on the foot brake pedal too or is it just the brake pedal? Have this issue on my van and while i accelerate it always comes on and warning sound stays not unless i stop.
While you had that level sensor unplugged you should start the truck. if the light is out the level switch is stuck or bad. Check that the e-brake pedal or lever is fully released. watch the light and pull up on pedal or push lever down. watch the light see if it goes out. Light comes on if there is an unbalance between front and rear brakes. maybe leaky wheel cylinder or rusted brake line. might be the Master cylinder leaking inside or to the outside look for brake fluid where the master cylinder bolts on.
@@BLAKHARTFILM If you ran it dry just start over bleeding. Level switch should reset itself when you fill the reservoir. If not and the light goes out with the sensor unplugged then just leave it unplugged and check the reservoir level more often like we did before there was a level sensor. I've found the most common reason the light is on is because the proportioning valve has sensed an unbalance between the front and rear brake pressure (leak somewhere?) It's below or beside the reservoir and has a wire to turn on the light too. Then of course, things can get more complicated with ABS brakes.
Yeah pontiac G6 V6 lmao my brake light comes on but when i turn the car off it goes away but when some times i drive it pops on it came on after i took a launch yesterday
Just wanted to say thank you. This was happening to my 2004 Jeep Rubicon. I pulled the sensor below the Master cylinder and it was full of corrosion. I cleaned it up with all the brake cleaner and reconnected it and sure enough the issue with the brake light coming on and beeping is gone. Thank you!
I am on FIRE listening, reading looking seeing videos of issues with break lights. I brought a 2021 KIA GT June 2022 and having the same issues with my car. My break lights only work when I use my beam light if that makes any sense, just all kind of back light issues that I should have zero F issues.
When car is on and hand brake is up hand brake light is bright on the dash when car is on but when I release the hand brake it goes dim red , some times it off then dims flashes , it does that even when all is switched off , what could it be ?
I have an 04 Silverado and today the brake light came on and started chiming. The brake fluid was full and I mashed the plugs to ensure they were firmly connected. I'm guessing it must have been the plug because afterwards the light didn't come back on.
i still need help. 2006 nissan tiida and the brake warning light is still on. changed master cylinder. readjusted brake shoe. bled brakes. checked brake pedal. all to no avail. help needed!
I added brake fluid because it was low, the ABS light turned off but the brake light was still on and blinked. I put my truck in park, set the e brake, released the e brake, and the light went off. try that.
xCAPTNxBACONx hey. I got the problem fixed tonight. turns out that the hazard light was disconnected and because of that the ECU saw that as an error. (I'm assuming) the light is working properly now
My 2004 GMC sierra starting today has a Service Brake system light and parking brake light on after bleeding the brakes with the engine running did I possibly ruin my ABS Anti-Lock Brake module or are both of these lights on due to air still being in the system? I checked the engine codes with my code reader and there are no codes available.
Thought there may be a way to reset the brake light. I changed a front left caliper, bled the air out f it but it's staying on. 2006 Hyundai Tucson is what I'm working on & I forgot how to reset it... I'll keep searching CZcams for the correct video.. Good video though..
Question can my aftermarket deck cause my e break light to come on? My e break comes for a few minutes then turns off randomly. Once this started my phone stopped connecting to my deck's Bluetooth. My mechanic said I had a code saying power to my radio was bad but my radio was working fine minus connecting to phones Bluetooth.
1996 Chevy blazes docent have a level indicator the master cylinder i have checked every thing i can think of i have a good brake pedal brakes are neww in the front and shoe brakes are still good as well still have the red light of death
If the fluid is low then your brakes need replacing or you have a leak. If you top up the fluid you will need to remove some fluid when you redo your brakes or you will have it pouring out onto the ground. people need to research what to do before they undertake any car repair.
I have one, I have a 1992 Suburban 1500 with the 350 TBI V8. Every once in a great while the brake light comes on, it's done it 3-4 times since I got it about 7 months ago. Usually going over a bump. Now, when I shut it off and go to start it back up, it cranks harder, like its getting spark but not gas but it will eventually start. The only time it does this, is after the brake light comes on. Could that be a possible short and where might that culprit be? Again the only time it will crank hard is after that light comes on, every other time, starts up perfectly with no issues.
cade hudson I picked up a 93 GMC Sierra, did the same thing. Turns out the only way to get it to shut off is to bypass the ABS. The shop disconnected it under the master cylinder and I have never had another issue. I have regular non-ABS brakes now, which I prefer anyway.
hi car guys, single mom of 3, I need a cheap fix, a DIY! my 97 Ford escort brakes work just fine if the car is off but when the car is on I have to push the brake pedal all the way to the floor! I have checked the brake fluid, it's full! any help, thank you! FYI, I only have basic knowledge, so a step by step maybe better!
I have a Pontiac Prix and I've had the abs light on for the past year or so but the break light just came on..do the abs and break light come on together or does it matter if they come on in conjunction.
I did everything you said and light is still on. Fluid is topped off. Jingled the brake pedal all the way. jiggled the master cyclinder fluid and its still on. Is it possible for my 03 ram 1500 that the brakes might be worn? Even though I dont hear anything when i brake.
Bro if you’ll tell me all this, then tell me what it means when I turn on the car then I press the brakes until they pedal gets hard and then the parking brake light comes on after I turn off the car and then turn it back on, the light is off. It only happens when I do that and then when I press them till they get hard bf a turn, I’ll heard a scraping noise. Nobody know
Did you bleed the brakes at all four wheels? Also, check the ground connections for the controller. Check for vacuum leaks at and to the brake booster.
Can be 3 reasons: 1)Low fluid level in brake reservoir; 2) electrical short )broken wires) or 3) a brake fluid line pressure differential. Check fluid level first then if not that, check each wheel to see if brake calipers, brake lines or brake cylinders are leaking. Look for tell-tale fluid loss i.e. drips or 'wet' areas. Can also mean master cylinder or ABS system is malfunctioning. Have shop apply DRB scanner to id the issue. Good luck!
Could be PB switch- something you can check/examine Here's link. Check brake fluid reservoir 1st-low fluid from worn pads often triggers the lite. if all else fails on the EZ stuff, have a brake shop scan the system with the DRB to ID what's wrong.

If your brake fluid is low it means your pads are low and the pistons in the calipers are all the way out and that where the fluid went or you have a leak somewhere

Try bleeding the brakes at all four wheels. Make sure you do not run the reservoir dry.

Mandie Cain if there are no leaks at the wheels from calipers, wheels cylinders or brake lines then you have a bad master cylinder.
Probably you need to bleed your breaks
Air in the brake system, need to bleed brake lines. Find the video for brake system bleeding by yourself.
