Gravity bleeding the clutch master and slave cylinders

Alrighty, I plan on replacing my clutch master and slave cylinders due to a disengagement issue.

It "seems" that if I pump the clutch pedal a few times when the clutch is not fully disengaging that the symptoms go away.

I have no pals and no one to help me.

I would like to gravity bleed both cylinders. I have done plenty of searching on the subject here, but don't get one thing.

How do I know that it is time to stop bleeding?

When I replaced my slave with an aftermarket one, I saw no air bubbles whatsoever.

How can I tell that I am done gravity bleeding?

It is obvious that I don't want to let the master run empty, but after that I am lost and don't want to put it back in too soon and have air in the line.

Thanks!

Re: Gravity bleeding the clutch master and slave cylinders

just let it drip for a while, watching your reservoir and topping it up as needed. after you've run maybe half a bottle of fluid through, tighten up the bleeder and test your clutch. if it works, you're done. if not, do it for a while longer. you may have to pull the clutch pedal up the first time; i've seen them drop to the floor the first time you hit it but then it's fine.

Re: Gravity bleeding the clutch master and slave cylinders

You can also get a brake bleeding vacuum suction pump thing. That would work better and faster.

Re: Gravity bleeding the clutch master and slave cylinders

I bought one of those brake bleeder pumps for about $50. It was the worst $50 I ever spent. I would highly recommend using the old brake fluid in a bottle with the hose submerged trick.

Re: Gravity bleeding the clutch master and slave cylinders

I got one of those miti-vac ones, and I ended up using a water bottle and fish tubing...less messy, holds more.

Re: Gravity bleeding the clutch master and slave cylinders

All that stupid pump I bought did was leak like a rusty bucket. Total waste of money.

See when I gravity bled, It just seemed like I had no issues with my clutch wayyy to fast.....e.g. in about 20 minutes or so, not the hour that I saw others post.

(Keep in mind that I just replaced the slave, not the master)

Is that normal?

Just makes me wonder
