How to get bleed air out of a clutch master cylinder

This was a 2008 Mazda 3. This is what you can try to do if you have bled the clutch master, lines, and slave, and the pedal is still spongy, or low, and you can usually pump the pedal up to get it to work because there is still air trapped in the system. This how to video does work on other vehicles.

After trying to bleed the slave for 30 min. I found this video and after 4 min of work. Boom! It was done. You sir are a god among men! Thank you!

This whole video is like a fever dream.
The camera movements really sell it.

Thank you. This procedure actually work for me but I used a modified version. I got a little bit of air out of the master cylinder with your version. But I still had a very soft pedal. So with the pressure still left in the slave cylinder, vice grips still clamped on the hose, I opened the bleeder at the slave cylinder and quite a bit of air came out. After a few times of doing that the clutch pedal was back to normal.

Worked great on my 86 Chevy K30. Thank you real time saver, I had been bleeding for hours with no results, ten minutes after I watched I was driving the beast.

Wish I had seen this last night. I spent 4 hours trying to bleed my clutch. Thank you for taking the time to make this video.

Reverse bleeding up to the master cylinder reservoir instead of down to the slave cylinder bleeder valve so basically the vise grip is acting as the bleeder valve this is genius gonna try it tomorrow thanks.

So glad I came across this video!!! Spent 3 hours bleeding the clutch in my civic and only got half a pedal.. Gonna try this tomorrow! Thank you!

Great technique, I did this 3 times on my Ford/Mazda junk, sucked in about about 100ml of fluid. pedal is firm & higher bite point. Thanks RBA. Dead head FTW

[johutson]

This was great! ‘Dead heading’ worked on my ‘07 Ford Focus. I was struggling to get all other types of traditional clutch master cylinder bleeding to work. Appreciate the help...you’re a good man!!

You sir are a god send, spent two hours trying to bleed my mazda 3 and wouldn't have thought of this! Thank you!

[WellWisdom.]

Thank you man! I will try it in my Frontier 2005 that no mechanic has been able to fix. I replace the slave and master cylinder and I was about to replace the line as-well.

[wojdan]

Thank you, that helped
FYI, it also works for 2001 Toyota Celica,
The elastic hose is behind the air filter and is moderately easy to reach.
Hope this helps someone! 😊

After exhausting every other method, I remembered watching this the other day. And blow me down if it didn't work for me too.
Cheers mate!

Thank you for the video. Definitely saved me I was going to take my car to the shop tomorrow. I also figured out away to remove a rusted stuck cv axle without any air tools. All you need is a small tourch to heat the bolt, and and I used my own car jack and breaker bar.i put the handle of the breaker bar as close as I could to the jack. Pumped it three times and the bolt broke lose. 2 days of staring at it and it finally hit me. I jack have Ron lifting power. Peace of cake

You giving all the tricks away lol it’s brilliant when people have a go and no joy then I turn up do the same angle the car clamp then pressure so bubble up out the reservoir job done then I hear rocky song in my head as I walk away lol

[zachary]

Just what I needed. Will try it and hopefully my car will be fixed

"if you have no flexible hose, you're pretty much screwed"

lol okay good to know, guess I'll just continue pumping the way I have been

[jamesboone]

Thanks for the video! It helped me troubleshoot my girlfriend's car.

2007 Dodge Caliber with a "squishy" clutch pedal and no engagement into first gear.

LOL "If you have no flexible hose, you're pretty much screwed."
Great video and method! Thanks! I'm gonna try it on my '05 350Z. Praying for a flexible hose to be there.
