Clutch Master Cylinder Failure

[@maxcactus7]

You are a VERY good man, Peter! Many mechanics would have billed her for the entire clutch job while only swapping out the clutch master cylinder. Your customers are truly blessed to have you.

[@spelunkerd]

It makes me wonder how many clutches are replaced too soon, only to find the problem persists. Is there any screening test you can do, to easily to tell if your slave cylinder isn't getting a full swing?

[@Syre-ir7bx]

A few months ago I came to a light and wasn't able to shift into any gear which resulted in a tow. Shop says slave cylinder or clutch and recommend both since the transmission had to come out either way. This didn't fix anything. I've been back over 3x now and it's still not fixed so this is next on the list

[@Elderspy]

I took my 03 Subaru WRX to many shops describing exactly the same problem to them and they all suggested I replace my clutch and clutch fork. Thing is I had my clutch replaced about 50,000 miles ago and I baby the car. I knew it had to be a hydraulic issue of some kind because of the behavior. Watching this video both makes me feel much better and confirms my suspicions. I'm going to go out and do this job myself for ~$65 right now instead of the $1200 or so the shops wanted to charge.

[@rockbay79]

I always learn something when I watch Peter's videos. He truly is a Master Mechanic!!!!

[@wakepe1]

I just installed slave cyl and still on floor so I can’t thank you enough awesome video .

[@Mr.Thermistor7228]

This is EXACTLY what my clutch master cylinder did! It was very sneaking exactly like you say! No leak but only pushing out fluid right at the very end of the rod's travel! Thank you 🙏

[@larzalexander7364]

My clutch randomly failed on me and started getting stuck to the floor. I was panicking like crazy in the middle of a busy street. After seeing this I confirmed my suspicions. I may also replace my slave cylinder at the same time as the clutch master cylinder. Thanks for the amazing info

[@rightlanehog3151]

I'll thank you on her behalf ;-)

[@smurfleton6305]

I'm watching this now because my clutch has failed me today. The symptoms you mention with the clutch engaging too soon are all things that I've experienced but as this is my first manual transmission car, I had thought they were normal things to expect. Tomorrow I will confirm the diagnosis of my car but this is a hidden gem video for sure!

[@dalepremo3695]

You are indeed a treasure and this customer is fortunate she found you. Excellent diagnosis and a very nice explanation.

[@Mentorcase]

The first part of travel in the master cylinder is where it blocks the port to the supply off, then it will start to pump out through the line, when you release the pedal it moves back and opens the port to the reservoir again, if the piston is pushed too far forward at rest it cannot let the cylinder refill and will lose it's ability to pump the correct amount of fluid to operate the slave cylinder.

[@dalenebarr2971]

Hello why would the master cylinder fluid be black 1993 Toyota. 4 wheel drive? I lost all gears I couldn't shift.

[@globalmobile017]

Oh so that’s why O’Reillys has a lifetime replacement on those... I think I’ve replaced mine about four times..😂😂😂

[@mscir]

Next time please consider disassembling it and showing us the rubber plunger and the probably badly pitted and corroded metal cylinder. If the rubber broke down a rebuild could fix it. If the cylinder is pitted, was it from water in the clutch fluid corroding it? What was the reason for the failure?

[@VasyaIvanovichPupkin]

Had the same issue on my wife's '06 tC. I ended up wearing out the 2nd gear syncro. Now with the new master cylinder, 2nd grinds when you shift aggressively... So the advise is, do not delay this repair because you end up shifting with the clutch still partially engaged.

[@totallyrandomstuffandrevie9609]

Thanks, I have been wondering why my clutch pedal sinks to the floor in my 93 Nissan D-21. The lack of fluid loss had me perplexed. I bought a new master and slave cylinder and will be replacing this weekend. And NO,the term master cylinder and slave cylinder is NOT racist !

[@gasisthepastendoil]

Changing the master cylinder doesn't always fix the problem You can change it 101520 times

[@truth409]

Rough shifting has nothing to do with the clutch The problem would be the synchronizers If you are replaced the slave cylinder in master cylinder..... Replace in the clutch would do nothing for rush shifting What are people talking about?

[@chocolate_squiggle]

Wonderful. This is another topic I'd been meaning to look up. I don't mind you doing multiple videos on things like oil replacements because it's different on different vehicles, it's nice to see those differences. But you also manage a great variety of topics on this channel Peter. Well done on this fix and thank you again for sharing.

[@truth409]

Lengthing and the rod for better shifting and it won't work unless your slave cylinder is failing And that's how you know If it doesn't work then you gotta problem somewhere else

[@WeiFischer]

This is exactly what happened to my 2006 Scion tC. The first mechanic I brought it to didn't fix it right and I brought it back to him to fix and he just tried to adjust with the nut which didn't work. I would up taking it to a different mechanic who fixed it. The first mechanic lost me as a customer losing a 5 vehicle customer permanently while the 2nd mechanic just gained 5 vehicles.

[@vincentanoche8975]

Thanks tou very much sir. Big help for me. Although im honda user but i think its dsame.

[@salvadorpalma8173]

2000 for a clutch? Are you replacing the gearbox while you are at it too?

[@tube-dude77]

WOW I'M SO HAPPY I JUST WATCHED THIS VIDEO!!!! What you described is EXACTLY what's happening with my Honda Crv!!! Today i replaced the rubber and spring on the slave cylinder, and there was hardly any movement on the piston of the slave cylinder. So now i know to repair/replace the master cylinder!!! 😃 Awesome!!!

[@artofnoly9754]

Help... sometime in the future??? How about right now??? Mine is shat, and your diagnostic advice will be heeded. Thanks Man! You have saved me quite a bit of money, I would say.

[@Timberjo2]

Great video! Thanks for sharing such an unusual failure!

[@gvi341984]

Dealership part or Aisin because Auto zone have the worst plungers

[@daviddeaton1575]

Thanks to your video my 89 GMC doing same thing I first thought it was the slave cylinder changed it no differnts But when you said master cylinder had black grim in it and leaking off Now I know what the real problem was after watching half dozen other videos no one else talked about black grim and leaking off when clutch was pressed in

[@hersonsariles5157]

I learn a lot from him too, very cool guy!

[@MustardTiger88]

Where are you located? I'd love to have you look at my 2005 Corolla CE. I'm in Toronto, Canada. Any recommendations for Toyota tech's in my neck of the woods?

[@st.thomasredevelopment]

Thank you so much. I watch your video and fixed my hylux clutch master. Your tutorial saved me 3k.

[@maximolotov]

Hei I have a leak under engine in the center Transit 2004, 2.0 tdcia Gear box got completely stuck 5 times already during last week. It begin with bad changing of gear 2. Some video suggests that release bearing must be changed and it is removing gearbox.

[@JacVisser]

Or you could just disassemble the cylinder and replace the rubber cups, which will be even cheaper, but then... most people are not mechanics

[@ezza200]

Thank you! That's exactly what my car is doing. I guessed it was the master cylinder, now I'm certain that it is - hopefully it is :)

[@sethfrazier828]

This actually explained exactly what’s happening with my car rn thank you for helping me confirm that it is just the master cylinder

[@noonanshane]

I'm assuming that everyone this helped owns a camry or scion tc?

[@DonBMW]

Priceless information. Same thing is happening in my BMW. It will not engage first from a stoplight. However, if I push the clutch pedal to the floor and hold 5 seconds first gear engages like butter. My master is probably bad.

[@fredpalacios507]

Save a couple of dollars 👍

[@v8pilot]

My Volvo 940 has the same symptoms so this video is very helpful to me. Out of interest, how exactly did the master cylinder fail?

[@thestephen8]

I hade my clutch replaced in 2018 on toyota avenis 1.6 vvti and it cost 260 euros parts and labor in Ireland

[@endlesstwisties]

I know someone doing it for 10 Euro + the cylinder But i will do it myself :)

[@everythingvideos24]

How to tell the difference from a bad clutch master cylinder from a bad master slave cylinder? I think I may have a bad clutch master cylinder because my brake - clutch fluid uses the same reservoir and when I checked it all the fluid was gone. My clutch pedal goes to the floor really easy, and the engine starts up, but it doesn't come back up unless I pull it with my foot.

[@gausselim1474]

So crazy... this is exactly what is happening to me right now!! My 2010 Toyota Tacoma V6 has had a difficult time shifting lately. There are NO leaks anywhere and no clutch slipping. So, I changed out the Slave cylinder and bled the system 3 times; the last was with the pressure tool. There was a lot of muck in the drained fluid. I had intermittent smooth shifting but it would keep reverting to a stiff stick. So, my next choice was to replace the Master cylinder. I just bought it yesterday and will replace on Saturday. Low and behold, I watch this and now believe this is definitely the issue. I thought I had an air pocket/bubble issue but it was the Master cylinder all along!!! Thank you so much for this video and clear explanation.

[@hokz7283]

Thanks. I changed the clutch disc and pressure plate a few months back. Soft pedal 80% and hard the remaining 20% when clutch is depressed. Sometimes clutch disc engages quickly with just a little bit release and sometimes when the pedal is released half way up... inconsistent clutch bite level. Clutch hardens when hot. The mechanic wants to replace the pressure plate again as he suspects fingers have turned hard(??). I have ordered for cylinders.

[@pedrofernandez8729]

What vehicle was it?

[@camwhitman5425]

Excellent video. Thank you so much for sharing your wisdom.

[@lito7263]

My 1999 Honda civic Dx hatchback 5 speed makes grinding noises when I have the clutch engaged. When I drive and let go of the acceleration the car starts to make grinding noise. I asked my mechanic had he said it can probably be my clutch master cylinder and I wasn’t sure if it was true or not. Can you help me find out what’s wrong with it?

[@bengtianyap4689]

thank you for the explanation! . This is probably my problem too but at very early stage. Occasionally and randomly my clutch refuse engage and there was some rough shifting. My mechanic made a quick check upon request but there was not external leakage at the rod. The piston seal (internal) and not rod seal (external) failed that does not allow sufficient pressure to actuate the clutch.

[@mrs.childers8333]

My car clutch is not to floor. And it sounds like it’s going in gear but nothing happens. It won’t move. I can smell a strange burning. Would u think it’s clutch replacement or slave?

[@ivorywhite7161]

Mines is spraying brake fluid all on the firewall. Then the clutch goes all the way to the floor if the brake fluid reservoir isn't full. After about 20 min of driving I noticed a about 20 percent of the fluid is gone already

[@dsingthermals6931]

I put a brand new clutch master cylinder and a toolbox and checked on it a year later and the Piston is locked up like it's full of glue I hit it with a hammer and it won't even go in it's completely locked up and this was a brand brand name clutch cylinder but it came from RockAuto

[@maco6298]

Fix an 80 series land cruiser please (‘97)

[@427yenko67]

I have a 2004 Silverado with a 4.8 and 5 speed manual...this is exactly what happened to me.

[@sidonio123]

I think I have a similar problem no leaks but when is hot weather the clutch just fill spongy and sometimes har to get into gears especially 1 and second gear.i bleed the clutch yesterday and still the same today

[@markreynolds3850]

Thanks for sharing this video great information provided.

[@vegaf2011]

What type of fluid is recommended for the master cylinder?

[@jonnyjaywalk]

Think this may be what my issue is. I got a new master and slave cylinder

[@ThePwak007]

My clutch master cylinder came with a packet of pink grease. Do you know where it goes? It says the cup of the clutch master, in not sure what the cup is

[@FernandoRodriguez-wu9hc]

I replaced one and now I have a similar issue I press on it and It goes all the way down, do you think the master cylinder might of come out defective?

[@shus369]

Good video. What about cars that have a clutch vacuum booster. My 1991 Nissan skyline GT-R has a weak clutch pedal and after pumping it 3-4 times the pedal becomes stiff again like normal. Already replaced the clutch master cylinder and slave. Still having the problem. Clutch engagement is good tho. No fluid leaks. Reservor is full. Pedal dose make noise like air is going in tho

[@gixer6847]

everything your discribing about the clutch getting closer to the floor is telling you its the clutch Slave and cylinder and maybe also the master cylinder not the master on is own

[@josefigueroa5088]

Wow what an amazing video. You’re a hero, a legend

[@tommybeady5976]

Amazing video!!! Need more ppl like you to explain every detail! Definitely helped me

Cut it open! Let's see how it failed!

[@BarrietteShekyls-c9t]

I'll try that thanks having same issue with my Hyundai

[@coreyjudd4676]

I did a double take at 0:52 'if you remove this 'Das Boot'..'

[@YKsBoxerGarage]

Can you tell me what Toyota came from that master cylinder, because it looks like exactly the same that my Subaru and maybe I got luckier look for a Toyota master cylinder than a Subaru in my City, here, subarus are very rare

[@Grandpasaab]

Hey my car won't let me get in gear when accelerating hard. Normal daily use it drives fine. I inspected my slave cylinder and it moves out instantly when I press the clutch pedal a tiny bit. Can my master cylinder still be faulty to not fully depress my pressure plate to not let the clutch disengage fully?

[@steppooncc]

Thank you, mate! You are one of the best!

[@junkemails5050]

Tnkx, helped me a lot, mine clutch master cylinder is almost like that. I thought was just air stuck in the system, i am still learning so i asked myself. Oh is really same fluid and reservoir for clutch and brake? I was surprised. But i had bled the brakes before. But wasn’t sure about have air still or not. Then i did a simple procedure to bleed out the master and slave cylinders, worked but i never saw any air coming off. Instead just had what seems a vacuum type of thing, don’t explain, doesn’t make any sense. So i just had to add more fluid. A good amount, did this through the bleed put valve on the slave cylinder. So pulling back the pedal would suck in the extra fluid. And was done and perfect working, well lasted for about 2 weeks or 3 and is already halfway again. I always notice since i got the car that the pedal is very stiff, even hurts the ankle. Its a jetta 1999 mk4 vw diesel 1.9 with 232.500 miles on it. Would a clutch pedal be normally very stiff . Another thing i like your accent, and the way you talk reminds me psychos in horror movie lol.

[@jddeefo1022]

After watching many videos on clutch hydraulics your is the best. I am a DIYer and for the first time I am dealing with a 2004 Civic Si with a clutch pedal that has no clutch pedal resistance, it goes to the floor and hardly returns. The car has been sitting 7 yrs without being used. The master cylinder was full and no signs of leakage. Should I just replace the master and slave? What is the simpilest way to try and bleed the system? Thankyou.

[@jtp0711]

Thank you for the video my friend!.

[@SierraOne]

Very sneaky indeed! Great Video!

[@zachary4225]

Hey I have a 09 Camry. My clutch pedal goes all the way to the floor. I replaced the slave and bled it the regular way by pumping and bleeding the nipple. The pedal goes back all the way to the floor. I haven’t changed the master but I’m not sure what else to check. What do you think it could be? Could it have more air in the system? I can’t shift any gears once I start the car. Car off I can shift the gears.

[@andrewhardcastle7982]

Thank you are a gentleman mechanic !

[@golgothapro]

I've gone through many in my 82' to 92' Camaro and I believe the "dirty" resevoirs are a sign the cup seals are abrading themselves against the fill port because they're too soft. What to do about it I've yet to figure out. Get proper internal snap-rings, build a jig to hold it for assembly, and get a line on some quality cup seals so I can rebuild the thing myself I guess. S has jsut gotten ridiculous and my pedal geometry is just as centered as can be. It's a real pisser man.

[@christopherjollie8988]

Peter, I am experiencing something just as sneaky as the problem you have encountered. Will try this out and edit this comment with an Update!!

[@zaimkhalis7682]

So what was your conclusion on fixing it?

[@wildwillscustomsexhaustvid9677]

Awesome video, I thought my clutch was bad when I couldn't get it in or out of gear with the car running, and would start to engage almost immediately. And at times would have to pump the clutch pedal repeatedly for a minute to get it to go into gear. I'm going to replace the master cylinder this weekend and see if I can save some cash, again thanks for the good informational video

[@pecosimplu7070]

thank you very much for this wonderful video, very good and clear explanations; it's really helpfull to me; this happens because people never replace fluid on that hidraulic system. big hug and whish you all the best 👍
