Brake Pedal Sinking? Dangerous master cylinder! How to fix

[@mygarden365]

Your explanation of the problem is very exact. Great content.

[@effie_ladure]

You did this!!! Great explanation! I am a DIY auto repair woman and just changed brake pads and back calipers. Had an issue with bleeding since the bleeder screw broke off... ugh... but needed a full awareness of HOW the brake system works in order to be more efficient in repairing... THANK YOU!! THIS WAS FANTASTIC FOR FUTURE USE!! Maaan... did a fantastic job!

this is the first channel to have a detailed explanation of the basic function of the master cylinder. i appreciate your video. i have a master cylinder on order

[@kingtut616]

I have been looking at a lot of videos to diagnose my spongy brake pedal. This was the most informative and easily explained, especially in describing the brake system and how it works. Thank you!

[@davidav8orpflanz561]

"I cut out a big hole in the floorboard in front of the driver's seat, which I can extend my feet through, and use my foot soles as friction pads on the ground to stop! If I'm going to haul a trailer, I have a passenger do the same with me, on that side." Modern Mechanic interview, 28,004 BC: FRED FLINTSTONE.😅

[@JMM599]

I found that strapping the brake pads directly to my feet vs using foot soles really saves a lot of money.

Very great video. Explained it very well. A lot of google info was useless or basically wrong. Your video solved my problem so sincere gratitude from me ☺️🙋

[@MisnadHaque]

Thank you and I’ll certainly point my mechanic to this. My civic has been suffering from sinking brakes exactly the way you mentioned for a while and the dealer had been skating over the problem citing worn brake discs. Resurfacing didn’t help and it still sinks. Explains why the Brake Hold system struggles too. Great explanation!

[@robertdeanda1961]

Thanks for the explanation of sinking brake peddle., I have to really check this out today I think like you mentioned I'm on the secondery safety one 🤯😳

I like your presentation. Good information. Well done.

[@BudgetMechanicHawaii]

Thanks!

[@legioner9]

Great explanations, as always. Quick and straight to the point. I would like to see how a brake master cylinder is replaced. My BMW has some weird braking behaviour, i.e. when I go like over 50 mph and brake really hard, the pedal sinks quite a bit, the ABS kicks in, but the car doesn't stop all that well, it travels more then I would like before it stops. Maybe it's just me having too high expectations.

[@BudgetMechanicHawaii]

Yeah it’s hard to say, abs is supposed to “reduce” braking in order to prohibit wheel lockup. So it’s a combination of tire quality, road surface, etc. That being said, it should stop sooner than you think since it’s literally supposed to maximize braking power…

[@alexandertabagari8564]

Nice and simple explanation. Thanks

[@williamorights4374]

Thank you! I've bled my brakes 3 times in as many days - no leaks, and still the pedal will almost sink to the floor. getting a new master cylinder.

[@adis8383]

Did master cylinder fix that problem

[@williamorights4374]

@@adis8383 Yes it did!

[@ironearl69]

Good video. Quick question ...I have good solid pedal with my vehicle not running. Once I fire it up and the brake booster is engaged the pedal falls nearly to the floor. I can slightly build some pressure back by pumping pedal rapidly, but not where it should be or the firmness that was there with engine off. I'm not seeing any leaks from the MC to the booster, but like you said it could be bleeding into the booster and has ruined the diaphram. Your thoughts?

[@DanielR44]

Did you ever get an answer to this? I'm a new driver and i've got a 2007 Renault Clio which has the same issue! I can pump the brakes when the engine is off and it becomes firm however as soon as I turn the engine on the pedal goes soft again and I need to press down quite far before the car starts to stop.

My car have no leaks. But I have no brakes. The brake fluid in the reservoir is very very dark watery feeling to it. Should I change the whole thing? Btw, it's a chevy comfort 2009 and parts are very difficult to get where im at. Aruba 🇦🇼 . Thank you very much ,the video was very helpful.

[@lockhamj]

Silly question, but do all cars have a brake booster, can't find it in my gs450

[@95almendarez]

Best explanation ever thank you sir

[@BudgetMechanicHawaii]

Most welcome!

[@SmudgyContent]

Was the rubber lines in the front. See I am so used to driving my truck around and anticipating that I gotta pump the pedal once as I’m come to a stop. It was pissing me off, watched Scotty Kilmer and he’s got one answer for everything, buy a Toyota. But yah. Bunch of brake work and still did it and a shop was like they’re fine. I’m like no… but anyway yah swapped out the rubber front brake lines and got a normal pedal for once. Took a minute to get used to it. About took eh bite outta the dash couple times. But yah. 👌 mint.

[@rabudman]

My pedal starts strong but slowly sinks as I sit. Been like this for months. Fluid level is below MAX but above halfway. I'd like to see a video on replacing a master cylinder on a 2016 Corolla. Front pads replaced 4 months ago. I replaced the rear shoes 4 days ago.

[@dailotom]

My friend's Corolla and my Civic had the same issue. Most likely the master cylinder or air in the lines if there are no visible leaks. Try bleeding your brakes if you haven't done so, could be air in the system. If that doesn't work, master cylinder probably needs to be replaced. Both of these are not very hard nor are they expensive repairs.. You should do it sooner then later. My friend left it like that for 3+ months and he almost got into an accident due to lost of brake pressure.

[@bonkeydollocks1879]

Its something you have caused when you messed with your front and back brakes, was it ok before you touched it

[@BudgetMechanicHawaii]

Is it very slowly? This could be due to abs module, but if it sinks in less than 5 seconds that not normal. I would suspect master cylinder. Air in brake lines will make it feel soft and spongy but not sink to the floor

[@rabudman]

@@BudgetMechanicHawaii Thanks. Now I'm thinking it's just air in the lines. It sinks slowly but not all the way to the floor and sometimes it feels fine. I'll try to bleed them soon.

[@mortonarkoi9365]

I love your presentations it's perfect.

[@BudgetMechanicHawaii]

Glad you like them!

[@DanyoPJr42o]

What would cause my brake pedal to be stuck to the floor when pressed but will slowly come back up? Master cylider or Brake Booster? I havd changed Front Calipers, brake pads, rear wheel cyliders and brake shoes. Also bleed system after all work was done

[@mrsmith5114]

Should brake fluid be coming out of the brake line if you are not pressing the pedal? I am replacing a wheel cylinder, removed the brake line, but I get a never ending stream of brake fluid coming out of the brake line that is disconnected from the wheel cylinder. Bit confused on that, thought you needed to keep pressing on the brakes for that to happen.

[@ISILENTNINJAI]

I got a 2014 camaro and i bled the brakes with ignition on of course. I did a complete flush with over 32 oz of luid so i got all the dirty stuff out. Anyways when the ignition is off its nice and firm but as soon as i turn on the ignition and pump the brakes i hear a wooshing sound and of course the pedal goes down easier more than normal. It still breaks okay and when im driving and brake it doesnt make the noise unless i pump it first before brakeing.

[@7evenPierce]

You might need a new brake booster.

[@raymondphan3806]

Thank you so much .. . .. You 're the best.

[@TheFermiumhalo]

Is there a way to tell if the ABS module is the culprit? I have a 2014 Q7 that has this issue, I recently slammed on the brakes as I noticed that the pedal was lacking consistency. After slamming on the brakes the pedal is now worst, I was told there is a way to bleed the air from the ABS module but I have no codes or errors from the module. Could it have no codes and still be the culprit?

[@BudgetMechanicHawaii]

Yes it is possible. Air in the lines often won’t throw a code

[@ScarabChris]

How about a brake pedal that doesn't come all the way back up but otherwise is fine. I had to really slam on the brakes last week. Now when I step on the brakes it feels fine and the truck slows normal. But when I release my foot from the pedal the truck will still be slowing down. But if I give the brake pedal a quick and firm stomp the pedal will return to the all the way up position and brakes are free. I have no problem stopping. I have a problem going after slowing for a turn or speed bump. Then of course when you try to go with the brakes engaged I get all the ABS and traction control lights.

[@cagr0311]

Have a car with very touchy/sensitive brakes. Suggestions? I barely touch the pedal and it breaks hard. ??

[@prince_of117]

Love your videos man. Solid info. Are you on any other social platforms?

[@BudgetMechanicHawaii]

Yes Instagram but haven’t done much there yet!

[@genoory5090]

What if you gotta pump it to get brake compression power? Could that be the masters brake cylinder or the brake booster?

[@kel57400]

I have a honda fit. The break travels a long way until i can start to break. No mechanic has said it was an issues but it is bothersome. Any ideas?

[@kovie9162]

Another cause could be the wrong master cylinder. For example many cars have different ones depending on whether your car has ABS or not and it really does matter. Also make sure that all your lines are properly and firmly connected and there are no signs of leaks anywhere.

[@Drayelam21]

Myn was sinking to floor, replaced the MC and now it's stiff and hard to stop. Idk if it's the booster cause I did the little test where you pump brakes, start it up and it sunk like it's suppose to. I'm lost

Hello! I hope you are well. My dad has a 2001 ford f150 and we have a sinking brake pedal problem. We have changed and bled the master cylinder, we also changed the brake booster, as well as the ABS module but the brake pedal is still sinking to the floor. We even changed all four brake calipers. We have bled out the brakes numerous times and gone through many bottles of brake fluid, but the problem remains the same. Are there any other potential causes as to why our brake pedal is still sinking? Please let us know. Thank you in advance! :)

[@ingridnicole1120]

In addition to this, when the car is off and we are pressing the brake, the brake pedal is firm. But once we turn on the car, the brake pedal sinks all the way to the floor.

[@jstephensoneyeOpen]

What if you have no breaking problem driving and stopping multiple times for about fifty miles... But two times apart from the multiple times the brakes worked the peddle goes to the floor??? No ABS LIGHT COMES ON! BUT CAN BARELY GET CAR TO STOP.

[@Trent52]

I replaced the caliper on my truck. I bleed that line till no bubbles but now the pedal go to the floor. You can pump it fast and it will build up pressure but it eventually goes to the floor again. Does this sound like air or mc?

[@BudgetMechanicHawaii]

Sounds like a leak or yes MC
