  post locked   How to bleed a clutch slave cylinder that has no bleeder valve?  

In all the years I've been repairing vehicles I never seen this before.
I'm repairing a 96 Dodge dakota 2.5 2wd 5speed that needs a slave cylinder.
I bought the slave cylinder and saw it had no bleeder valve, and the old one doesn't either.
How did they bleed this to began with?
Any idea's on how i can bleed this thing?

Thanks

Those are a PITA. What I do is take the master, reservoir, and line off the vehicle. On a bench have someone keep the reservoir full of brake fluid. Next, bench bleed the master with the line attached. Make sure the master is angled so no air can get trapped. Then take the slave and tilt it, so you can pour fluid into it. Once full, connect it to the line. Put the whole thing as one unit back onto the vehicle.





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Ok.., Thats a good idea.
I ended up doing this:
I had someone keep the clutch master cylinder full of fluid while i was uder the truck pumping the slave cylinder by hand, i removed the little shaft that comes out of it and put a 3/8x5" extension in there and put the other end on the ground and just kept pushing it down back and forth untill all the bubbles stoped coming out the the fluid reservoir.
The clutch pedel feels like butter now and it's nice and high.
So i didn't need to remove it from the vehicle, so atleast that saved me a little time.

Thanks for the reply!Cool

This sh*t can suk. Some just don't cooperate without tons of bad language and keep children away! With some used a vacuum pump to alter gravity!

I hear ya Tom.
Why in the world would someone ever have the bright idea to design something wihtout a bleeder vavle on it?
This is the only time I've ever seen this.., I've never saw chevy or ford do anything like this.

The way i did it worked great though, Guess it's just another "trick of the trade" huh.Laugh

I had to bleed the clutch master on a Shelby Mustang GT (newer style. 2007 I think) that had no bleeder. I used a rubber stopper (like a drain plug) that fit tight in the top of the master. I drilled a hole in the middle of the stopper and stuck a small metal tube in it.

With the stopper pressed into the master opening, I attached a vacuum pump to the metal tube in the stopper. I put it under 20 in. of vacuum and held it for a minute. I repeated this two more times.

Worked perfect.

You guys need to watch the dates on the thread. This one is months old and really shouldn't be commented on any longer.
