- I saw this trick on another video and figured I'd give it a shot. It seemed to work just fine and is probably possible with most cars.

Ive watched this about 20 times now , he explains smoother then other guy. Chill dude haha , hopefully it works for me
This worked great! Make sure and follow the Bentley manual steps to also remove and bleed the slave cylinder. Page 210-2 in the Bentley book.
Brilliant practical demo and glad you kept the original initial disappointment where it didn't improve much, gives us fellow spanner twirlers a bit of hope and realism!
Subbed!
I also try to show the real-ness in my videos. Sometimes stuff isnt perfect like a tv show lol
My man, not all heroes wear caps. I’m gonna do this on my e30💪🏼 💪🏼
Bro! I built a race truck. Swapped to a 6.2 motor, and a custom 5 speed transmission. The transmission was also custom built. The gear shifter has always vibrated and the clutch engaged very low. It was always a soft clutch. I thought that was how they designed it. One day...boom clutch had no pressure and won't go in gear. I see the reservoir is bone dry. The slave and master were new, with braided line. I do this exact thing but with a tiny syringe. Brand new clutch and shifter now. Clutch engagement is where it should be. Great pressure, and shifts like a dream. It takes a while to get all the air out but literally cost me nothing. If your in a bind... This works great.
Just dropping in to say thank you! I was struggling for a few hours before finding your video. I was so hyped after feeling so defeated lol
I absolutely need to do this. I have some pedal on my 6 puck, but not anywhere near where it should be. plus, i replaced the factory line with a stainless braided.
Thanks a lot, same problem and this works fine for E30, I tried others methods without luck, but this works pretty well and quickly
I forgot to mention that I had no choice but to do it like this. My situation was I test drove my truck for the first time after the motor swap. Re wired EVERYTHING from sound system to power windows to lights. Drove a long way because everything was working great. I go and eat lunch. When I got back the clutch had no pressure. Truck has a 5/8 drop on 24's. No way I could get under the truck without a tow or someone bringing tools. My wife brought the tube and syringe.
Just had this pain changing master on my e32. U can back feed it from the slave the same way too
I spent about a week on my Honda trying everything including vacuum pumping short of pulling my master cylinder off which is a total pita to access. I saw you and two other guys use an oil syringe for this so I'm going to try this and I'll let you know how it goes!
How did it go?
@@michaelcliffe562 I ended up forcing fluid through the slave bleeder with about 2atm of pressure with the syringe while simultaneously pulling about 2atm of vacuum via the reservoir line that feeds the master cylinder.
It was only when I did _both_ simultaneously that I started bleeding off significant amounts of air. As I suspected, I had enough of an air pocket in the master cylinder that it was preventing the fluid in the reservoir from flowing. Just pushing or pulling from a single direction only produced enough pressure to compress the bubble.
Now my clutch pedal is probably at least as firm as it was 26 years ago :D
Definitely recommend the syringe. If I had to choose only a vacuum pump or only a syringe, I'd go with the syringe. Using it without the vacuum, I was able to get _some_ clutch pressure, but not enough to fully actuate the slave piston.
I _never_ thought I'd spend over a week bleeding a basic hydraulic system like that. My neighbor's an engineer and he was starting to question his sanity over the whole thing too haha. Didn't think I'd end up at the horse store looking for tools for my car lol. I guess horses are technically hydraulic systems, now that I think about it....
Hope that helps if you're having the same issue.
@@ThorsDecree That is awesome! Thanks so much for the answer! I'm from Germany and I've been trying to bleed the concentric slave cylinder in my FWD Renault Clio for...well, about a week now! I've vacuum bled it, pressure bled it, reverse bled with vacuum and pressure from top to bottom and vice versa and nothing works! So this is the next thing I'm going to try as I'm convinced that the air bubble isn't even in the slave cylinder anymore.. I've ordered a sringe kit on Amazon and I'll let you know after easter. Again thanks alot for the reply!
@@michaelcliffe562 as long as you have verified that fluid can flow, that the line isn't blocked, it should just be a matter of getting the right amount of pressure. Depending on how your master cylinder is set up, jack up the front of the car or park on a hill. It'll help you get air out of the master cylinder.
Good luck! Btw, if you have any farm stores around, I used a horse syringe. Same tool, but the livestock store sells it for 1/5 the price an auto parts store charges.
Good luck, brüder. Let me know how it goes, I can relate to the struggle haha.
@@ThorsDecree yah me too, my damned volvo 740 slave is blown and a week later my master cyl spring is broken into two pieces, after fiddling and fixing the broken spring and seal clutch still not working and i am trying bleed from the slave cylinder. hope this method works cuz ive been working on it for 3 weeks just bleeding, i might tow this sucker to the shop if it wont work i just got no time.
I did this process maybe 4x to make sure all the air was gone after doing a new SS clutch line, slave, and master. Used the same syringe as in the video. Now I get a sponge soft pedal after hard driving. The firmness eventually comes back but clutch pedal gets softer after hard driving…guessing there’s still air in there? I checked for leaks and nothing, fluid level is fine
Same
Bentley manual page 210-2 Follow the procedure to bleed your slave cylinder.
so do i clamp the line shut before i reattach the reservoir
DIY nice. Need to try it myself ty
Very helpful thanks
I know this is a old video black but did you lose pressure once you put the hose back on the master?
No after putting the hose back I just topped off the reservoir again and felt the same
@@itsBlack thanks homie 👊🏻
This really works thanks
by any chance did you do the clutch slave cylinder? If so did you bleed it by hand first or just let it be and started the bleeding with the syringe? trying to get my e34 back the road but this job is a pain in the ass
What did you end up doing?
@@SleekM3 i took it to someone else thinking i was doing it wrong but it turned out i needed a whole clutch job bc something got bent and wasn’t keeping any tension (assuming the pressure plate was worn)
Useful .. I just did a swap. I wish I had thought of that. The clear tube makes wha't happening visible. In the final stages I wonder if removing the plunger would make sense, because at that point the air will float up and out anyway. I ended up unscrewing the slave cylinder and rotating the bleeder "up" instead of "down" (its operating position) That worked .. and I could see bits of air blowing out as my helper & I did that dance of "Open, shut etc "". What you did is better because one guy can do it.
Tks!
Where did you get syringe?
Where did you find the syringe
Hopefully this will work on the z3 also
Dude! Drop the link to this syringe!
Helped me so much!!
Do you leave the bleeder valve open?
Nope leave it closed. Your pushing the air bubbles to the top out of the syringe
Nice. Where can I find that syringe?
Search automotive syringe on amazon you should see it. It was $20 but can be useful later for diffs and transmission changes
I found one at AutoZone
Leave the slave cylinder bleed screw closed?
Yep. Everything will bleed from the top when you push the bubbles out
@@itsBlack I literally cant force anything through with the bleed closed, any ideas?
leopard headliner?
Heck yea man..!
This work with an e60?
Never tried but don't see why not!
Hahaahah !! HELL YEAH!!! 2:56
What kinda seats do you have in there !? They're 🔥🔥🔥
They are Vader's but redone in a custom color. A little darker than Modena
Bro got a life supply of break fluid
Don't know what i did wrong, no matter how hard i pushed fluid wasn't going in and air wasn't coming out.
I used a household syringe for like 10 mins and boom
What volume?
One important question is do you know JESUS CHRIST AS YOUR PERSONAL LORD AND SAVIOR?
