This is Why Your BRAKE Light is ON

[@oin42o2o6]

Thank you so much for this! My 2012 Subaru Impreza had the Brake light come on and off at random times while I was driving. Been that way for 5 months until it finally got bad enough that I decided to take a look at it. As soon as I looked at my master cylinder, I saw that I was low on brake fluid (right on the Min line.) Filled it back up and the light was gone for good.

[@ryumadbear7983]

Awesome! Straight to the point. No nonsense rambling of words.

[@bigdaddy5150sh71]

Great! I'm going out to do this now. Light was on when I replaced my breaks. And still on. Thanks. Didn't understand why. Thank you.

[@Colombo5218]

Superb video! You are a very gifted communicator. My 1989 E34 beeps continuously while driving. The sound stops for a few seconds on pressing the brake pedal and then starts again when I take my foot off the pedal! No one has a solution. All the best.

[@wackpackxj]

Thanks Brian. Wifeys brake lights been on for a month. Checked the fluid. Fine jiggled the ebrake. Stays on. This happened shortly after replacing pads at all 4 corners. But the ABS light is on too. Another strange occurrence is that the pedal is soft and goes to the floor after starting and hardens up after a couple depressions. Then continues to work fine. Also feeling a bit of wobble in the pedal as I roll to a stop. Checked all hardware, all pads still covered in meat. No overheating at any corner. 2003 grand cherokee loredo 4.0

[@shelvesetc7150]

Thank you very much Brian! I have the same problem in a Ford Taurus 2003, not anymore.

[@daveh5912]

I love your vids Brian, keep up the good work buddie

[@cabby0120]

This is excellent information. BTW you’ve had an excellent channel for many years. I don’t know how many but congratulations on a long run.

[@izzycamaro]

Thanks for all the good info on why the emergency brake light stays on. great job.

[@skymaine716]

Thank you for posting this video.

[@lesliem.8821]

Thx for the video. Informative and straight to the point.

[@sni1144]

When ever I do a disc brake job, I cycle the pistons in and out a few times, except I open the bleeder so it also flushes out the old fluid. Cycling the piston in and out a few times seems to help remove any varnish build up that may cause the piston to hang up in the caliper and prematurely wear the new pads.

[@deecee7447]

You're the man dude! Thanks👌👍

[@2LateIWon]

Also to determine (on some cars ) if its your reservoir sensor or e-brake sensor. It should get brighter if you put the e-brake on. If it doesn't get brighter its you e-brake (switch)

[@curiosity2314]

I have one to add to your list that happened to me recently working on my Ford Focus 2007 with rear drum brakes. The new brake drums do not come with the tone ring for ABS. learn the hard way I installed the drums without swapping over the tone ring. The dash lite up like a Christmas tree with traction control, ABS and the red brake lamp warning. Code C1235 and C1236, had me puzzled at first but with a little internet search I discovered the magnetic removable tone rings. I hope this helps others.

[@jeffrussell8051]

What a great video. Thank you.

[@daveradiofm]

Very helpful. Wiggled the sensor on the brake fluid and it doesn't come on anymore. Thank you very much!

[@davidhughes4728]

Really love the video man keep up the good work

[@tymesix]

Thanks alot....exactly what I was looking for. Thanks for your effort.

[@hollykauitzsch3095]

Nice details and explanations. Thank you

[@camarnold1506]

Good Informative video! I have a 05 Sebring that has the Brake Warning Light on. Cant figure out which of the two problems it is.

[@SteveRobReviews]

Good stuff Brian - some scan tools may show a pid for a on-off signal. Seems the more toys on a vehicle requires more toys to fix them. You can never have too many toys. :)

[@tulow9425]

THANK YOU VERY MUCH SIR. Problem solved Very helpful mate.

[@TheMistaneff]

Ty for the information. I'm pretty sure this is what has happened with my 05 silverado 1500. I let it sit way too long and it's having some issues. Was going to take it to a mechanic last week and the shifter linkage disconnected from the transmission so its been one thing after another

[@x21gokartracing]

Thanks, easy fix brake fluid reservoir was low

[@TTM719]

When I first got my 1988 C1500 on the road 2 months ago, my parking brake light came on and didn't flash. And now it's been flashing and it's been doing it since last Tuesday.

[@raymondsmith6943]

Thanks Friend, that's what I thought it was, because I had a full reservoir and everything else checked out. That was it ! Thanks!

[@mrich2245]

I just bought a 98 4RUNNER with the brake light on. I added a few ounces of DOT3 fluid and problem solved. Thanks!

[@pifas0813]

thanks man i will cheke that on my expeditiom my light for the brake is on

[@annagary72]

Thank u so much o figured out why my break light was on all of a sudden

[@edisom306]

That's how I do it also very good but I also take the cap off The master cylinder just to make sure that the air escapes because sometimes it can put air in the brake lines not all the time but I have had it do it before I never have after I start taking the Off

[@aaronhouston1982]

Just a general compliment. Your so good at showing how things should work and what might be wrong.. Also great at explaining how to resolve your issues. Thank you!

[@briansmobile1]

Thanks Aaron- I'm flattered

[@StvenMalinchak]

Good, informative video!

[@mikelaplante7873]

Helpful! My Windstar threw lights on everything all the time. 20 years, original owner, 60K miles, and the electronics just all started failing. My Grand Caravon just lit the brake and ABS light. Code reader showed "no codes". Fuses all intact. Here we go again.

[@khalonen]

Fun thing that I've found with my Subaru about the brake fluid level: Put in new pads every 4 corner, adjust fluid the way it's exactly at top mark in the reservoir. And then when the warning light comes on for low level, you'll find out that brake pads need replacing soon. That's with STI brembos, guess the caliper pistons pull so much fluid with pads wearing out that happens. I'm thinking the engineers never thought it that way and it's just coincidence.

[@jamiecharlesjohnstonms6493]

Good information!

[@GettinJunkDone]

On my older F150, the brake light also comes on when the alternator has failed. Learned that while driving to work a few weeks ago. Of course there are other symptoms present when this happens.

[@MatthewFant]

Great Info bro. Thank you.

[@briansmobile1]

Thank you!

[@johneric3886]

Nice work Brian's mobile one. I haven't watched some of your videos in a long time. I hope you're well. Know that I think very highly of you, and your character. Your goodness comes across in your videos. ____________I live in Ohio, and recently had a good vacation cycling up the West Coast of Florida. Jumping from hotel to hotel. _________Happy 2022 to you and your family.

[@masterjbrown]

It could also be a bad circuit board on the cluster. I've seen this on a Ford Focus and a Ford F-150

[@timtremblay7730]

Good to know - thanks.

[@alnuaemeaburawa7630]

thanks a lot , that was my case exactly, its been solved.

[@sixtyfiveford]

Good tips.

[@briansmobile1]

Thanks

[@dans_Learning_Curve]

I believe the brake warning light also comes on with unequal pressure in the divided brake system. If one half of the brake system should fail, develop a leak, the light will come on.

[@richardurieric8502]

good video!, thank you for sharing!

[@TravisHeinze]

I have a fancy sensor in my brake fluid container, but it doesn't seem to work when I'm low.

[@gardenstateflatlandb]

My brake light is an enigma. Brake fluid is full and fresh. Brakes in perfect working condition. Also fresh parking brake cables. Today I swapped out the parking brake switch, and STILL have that annoying brake light on the dash. Any clues what to look for next? Thinking MAYBE the wire going to the switch? Forgot to slap the probes on it while I had the center console out. Any tips on what to check next would be much appreciated.

[@andrewdomenitzdmd]

Mu toyota tundra had a plastic plate break out where a push button switch needed to be depressed in the brake pedal arm under the dash. It caused my rear brake Lights to be on all the time so you could not know if I I was braking. The brake lights in th rear were on all the time.

[@ApexHotShot]

Hi Brian. I am glad I found your video. I spent today doing a radiator flush, new hoses and t''stat on my wife's 2002 Taurus. After I checked for leaks, I dropped it off the jacks my wife took a test drive. Well, we were almost home and she noticed the brake warning indicator light was on intermittently and then stayed on. Of course I had to explain that radiator work would not affect the brakes. The fluid level looked perfect and I was beginning to think the float switch was the issue .. until I saw your video tonight. I set the parking brake after getting the car on the jack stands to work on the cooling system. Maybe a bit too forcefully. I will check the parking brake switch in the morning. Thanks for the lead on the problem. (So, maybe my radiator work did affect the brake system.!!!).

[@nayoayala161]

This helped me 🎉😂

[@Hyrule2007]

I have this problem on my 04 STi. Its not the hand brake because the brake light illuminates brighter when engaged and the master cylinder is full. Are there any other ways of finding out why its not clearing off the cluster?

[@ramonmurillo1936]

Hope this helps been dealing with my break lights going on right when /(or a while after ) driving around. Considering to buy new headlights and break lights housings... doesn't feel safe to drive around most of the time ... even less in the day when I can't see my break lights going on

[@mohammedal-hawaj9105]

i have same issue with my 1991 k5 blazer, which is the brake light always ON inside the dash ? any advise ? oil brake level is good

[@jjphank]

Thanks ,helpful

[@senorlisenciado9924]

Tanks man...👍👍👍

[@ken3marcus]

OK, I went to wiggle the sensor on the master cylinder, and the wire was completely out there! Thanks For the video!!

[@davee4990]

Great very helpful thank you

[@edccstudent]

I have a question, when pressing the piston, do I need to remove the master cylinder cap? If I don't remove the master cylinder cap, isn;t there have pressure inside the system?

[@johndutton4860]

@My Daddy yes always remove the master cylinder cap when manually pushing the pistons back in

[@baddoggie101]

Your rear drum brakes have an automatic adjuster that works when you back up fast enough in reverse and step on the brake hard enough. Most people don't do that fast enough or hard enough to cause the adjusters to do their work hence your brake system may detect the maladjustment of the rear brakes. That happened with my vehicle. The solution is to find an empty parking lot, back up quickly (maybe 10 mph) and step on the brake hard. Repeat five times or so and the light will turn off. Worked for me.

[@PreciousMetalinvest]

Might try this, I reversed and put up handbrake... in a fast motion as I wanted to get car out of the way of the narrow road, then this problem happened

[@ujayet]

Will definitely try this

[@skyleramella5728]

Interesting. I've got a 1990 mazda pickup and had my hand brake engaged backed up 2 feet before I noticed. Now my brake light on dash stays on. Might try this.

[@phillpennell311]

Interesting comment at the beginning, my 2004 MINI Cooper S has the brake booster and master cylinder directly in front of the driver on the left side 🤔

[@allthingssilver7635]

I had a brake line rupture and lost all my brake fluid. I replaced the brake line along with 3 others, bled my brake system and topped off fluid but my brake light and TC light are still on. Will they reset themselves or do I have to have them reset with a scan tool? It's been 2 days so I feel like if the lights were going to reset themselves they would have done it by now. Vehicle is a 2005 Cadillac escalade ext. My dash display also reads service brake system and stability system disabled.

[@anthonyfili11]

Is it possible to get a brake light that comes on because of abs light?

[@zeeek1]

On my 2002 Monte Carlo either the float switch keeps sticking or the Parking brake switch system is fouled up because my light comes on intermittently. My car is know to have electrical connection issues.

[@enockopoku9974]

I had a brake light and I didn’t realize my handbrake was pulled out. Thank you for that clue. It worked for me. 👏👏👏👏👏

[@pegasz]

You beginner driver..

[@lilroyyy2779]

Enock Opoku bruh!

[@joel61121]

Well you have fix my problem thank you I was wondering why it was coming on while I was driving and then goes away and it was bcaz I replace the caliber and but never to dot3 on my container to fill it all the way to the safe fill lol

[@damienjameszimbrick]

Hey awesome video! I have a Ford Taurus as well and this just happened to me yesterday! My fluid is fine but that light stays on i haven't checked the plunger you showed in the video yet. But if that is the issue how would i fix it?

[@AzusaMan]

Hey Damien, did you figure it out?

[@abmakmur]

Great video

[@jeffgadino8187]

great video ,fixed my ford transit, no more brake light when I make a turn.thanks jeff

[@samuellopez3813]

Thank you

[@coolio8444]

This also comes on with brake pad sensors correct?

[@raymathews7035]

Would this also cause the ABS light to come on? I notice that when you pushed on the caliper (pushing the pistons back into the caliper) so you put the brake fluid back into the master cylinder, that fluid had to go back through the ABS motor, which could clog up the fine holds in the motor and cause other problems. Don't you need to release the brake lines( loosen the fittings) so that the fluid doesn't take the chance to plug up the motor?

[@danielreynolds178]

What usually makes the abs light come on is a speed sensor on the wheel bearings in the front.

[@XnazxulX]

Can the brake light come on due to transmission fluid being out? My brake light has been coming on and off and tonight my car just stopped moving when I was in drive wouldn’t even move when in reverse either.

[@carlosleiva9406]

thank you

[@jorgetrevino5757]

Hi and thanks I saw that switch off and I put it back fix it for a moment but comes the light on

[@mauricegoz]

amazing how there were clues and i couldnt put it together

[@leeenglish6176]

My brake light was on because I had removed the abs light bulb out of cluster on my 03 jeep grand cherokee. However when u remove the abs bulb light it will then cause your brake light lamp to illuminate.

[@emomisty1993]

My brake lights work fine when my running lights are off but when you turn on the lights the brake light turn on as well

[@lizandrovaldez4928]

I have the same issue and i havent found the problem any luck your way? @misty gregory

[@solomonmuchanga]

Dear, i have Lexus Is200. the brake lights on dashboard when i press emergency brake pedal, but the hand brake function quite well, when i push it on the light comes on and when i press down the lights comes down, when i press brake pedal the handbrake light comes on and doesn't switch off untill i switch off the engine... The brake fluid is Ok! please can you help to fix it?

[@Imwright720]

Npr diesel amd the switch works. It also turns on and off the lights. Cannot find any problems with it.

[@danisduarte89]

great video

[@bicycle697]

can't wait for the tractor!!!

[@nicholascooper2717]

Like Robert said above Don't push the fluid in the line backup. Let it drain through the bleeders. You risk damaging the abs system by doing it the way you are showing

[@briansmobile1]

I appreciate you looking out for me Nick. I've heard that before, but in the thousands of brake jobs I've done this way I have a 100% success rate without damaging a single ABS system. Now muffler bearings and blinker-fluid system leaks... not so good! ; )

[@cosmowarriorzero3530]

Brake light was on the Dodge Neon my wife drives. I checked the brake fluid level and it was low. I added more fluid and the light went off, but after I pumped the brake pedal a few times after adding the fluid there was small puddles of fluid under the car in the drive. I also checked the emergency brake, but it was not in use. Curious why the fluid came out unless there was too much added. I was careful not to overfill it

[@cosmowarriorzero3530]

Also of note: When the break pedal was depressed it wasn't as tough as it has been in the past. Do I need to have them bled or is this common. It's almost as if I have to push the pedal all the way to the floor panel to get the vehicle to stop, but it gained more tension once I added the brake fluid

[@cosmowarriorzero3530]

Got it fixed. Thanx

[@jamesjones6297]

[@sheilajefferson503]

I havea nissan Xterra, i replaced the Relay and some of the chips, n parking light still stay on and head light wont work unless i hold high eam, n i checked the break pedal and Thats fine

[@donaldcoxe946]

That's not the problem. Switch has been changed new pads and calipers. There is some other problem. I think it's in the emergency brake handle.

[@seventhson27]

I had this happen to me. Was weird. The "brake" indicator would come on, but when the weather warmed up, the light would go out. Then I found this video. I checked the brake fluid and it was not low, but it was not full either. I topped off the brake fluid. Problem solved. I suspect the brake fluid level was just right on the edge of the light coming on. When the weather warmed up, the brake fluid warmed up and expanded just enough that the sensor would detect it being "good."

[@AngelRodriguez-hi9em]

Emergency brake handle 🤦‍♀️ (you saved me bro only thing I forgot to check)

[@VWfreakVR6]

I had a 91 mazda 626 some 12 years ago that the brake light was on and after checking everything i found out I had a stop light blown! Changed the bulb and the brake light went out. Wish more cars were like that!

[@erikflores6092]

my emergence break keeps coming on and off when ever it wants to. can some one tell me what that might be...?

[@taylorsterba1351]

So what if you don't fix this issue will there be severe consequences and quickly or no because it's been a month and I have brake light on and I haven't fixed please respond thanks

[@jimwagner417]

No worries

[@cindylong624]

thx!

[@kl2469]

Be careful with calipers. They hold tremendous force if lose. Can become projectile or smash fingers

[@qwertyasdf3696]

+Kacper Litwin thanks for the info

[@robertgray6512]

So... what fixed your light?

[@eth232]

What about the doors light on at the same time with the brake when start the engine

[@arikoenig4536]

I changed my rear pads on my is 300 Lexus and now when I engage the parking brake the indicator light on the dash doesn't go on anymore any ideas?

[@arikoenig4536]

Where is the parking brake switch? Near the rear pads?

[@shitolechandru]

While driving and stop at red signal break light notification ON and OFF after ~8 mins. Is this same issues?

[@jarinwilson9539]

Just keep in mind that some MC's are finicky when it comes to forcing fluid back in them. I have seen MC's ruined because of this. Here's a tip, if you run the risk of snapping the bleeder screw off, loosen the banjo bolt and bleed it from there.

[@jordandowns170]

That still doesn't bleed out actual caliper completely... only hose and portion of caliper..need fix the actual problem. No disrespect just a tip

[@williamgeorgelopezjunior8533]

I thought I was crazy for making a “Caps” container... but now I know I’m not. It helps!!

[@anthonydavis1320]

My brake indicator light is on and my car won't move ..I just changed caliper and brakes and rotors

[@sulemanhassanali]

My Chevy Optra/ Lacetti 2004's brake warning light comes on when I apply the brake first time after starting the vehicle and then stays on. ABS light goes off stays off once I start the engine. Can anyone help? I dont feel any problem in braking and brake fluid level is also okay. The light comes on after applying the brake and stays on. .

[@ab30494]
