Bleeding Slave Cylinder

jcook009 · #1 12-31-2006, 02:26 PM

I just replaced the clutch slave on my 2003 F-150 4.2L 5-speed.
I have tried bleeding it the same way i would bleed hydraulic brakes, but with no luck. I even tried freebleeding it, but it started coming out of the reservoir. I don't know if there is a certian way to bleed a hydraulic clutch, cause i never had to mess with one before, or if it could be that i just suck that bad. But if someone knows how to do it, it would help me a whole lot.

I'm not sure what you meant exactly by the last sentence above, but. I found the best way to bleed a clutch slave cylinder is to simply gravity bleed it. Fill the clutch master cylinder, open the slave clinder bleed valve and let the fluid run out. leave the top off the master cylinder so you don't create a vacuum lock and don't let the master cylinder go empty. After you feel all the air is out close the slave bleed valve, top up the master cylinder, replace the top and you should be done. Hope this works for you.

Well thats what i meant by freebleeding it. When i opened the valve, the fluid started overflowing from the reservior. Dont know if it is because the valve is higher up than the inlet, but it did just the opposite of what is was supossed to do. Nothing is a simple task with vehicles anymore.

If your feed line is not seated correctly in the slave it will build up pressure in the line and cause the reservoir to overflow. Try pulling on the fitting at the slave and reseating it.

If the feed line to the slave is not seated oil will not flow to the slave. see pic.

Well come to find out when I was filling the reservior, I was actually filling the rubber piece inside, I forget what it's called. So when I removed it and added fluid, behold I got fluid down into my slave. It's amazing how stupid I can be sometimes.
