Hey gang, as many of you saw in the other thread, my clutch slave went south. Pulled the trans yesterday afternoon and found that the throwout bearing had gernaded itself causing the slave to puke all it's fluid. Got it all back together. Now the deal on bleeding the clutch slave -

According to the Ford manual, you need to attach a vacuum pump at the resevoir and bleed it that way. I did not have time to fool with that last night, but this morning, I jumped in the car and pumped the pedal a few times and all of a sudden, perfect pedal! The slave had basically self bled when the car sat overnight and after a few good pumps of the pedal, it was completely bled. So at any rate, it was much easier than I thought, especially when I was thinking I would have to bleed it at the trans, where you cannot even get to the bleeder screw to crack it open.

when i changed my clutch i didn't have to bleed the system either... just jacked the drivers side up and pumped away - ended up with perfect pedal pressure !

ya you can either bleed it and be cussing

or just grab somin to drink, and sit in there and pump it for a while.

Pump very slowly with the driver's side jacked up. Once the air starts to bleed out and the pedal starts coming around you can begin to pump a bit faster, but keep it kind of slow. The air needs the chance to escape through the port in the master cylinder.

I need to try this with my stang - so basically you jack up the drivers side about 8 inches or so and loosen/remove the cap on the master cylinder before you pump the clutch?

How do you get at that cap (not near the car right now)

After pulling a few '05-up trannys...I've found that putting some vacuum on the master cylinder for about 60 seconds and then releasing it and pumping the pedal about 15 times...and then repeating this process about 4-5 times is the fastest way to get all the air out. Basically this is just a simplified explanation of the Ford Workshop manual.

Can I just find one of these pumps (that they show in the service manual) at a Pep Boys or Discount Auto parts??

Yep...all you need is the plastic Mity-Vac ($20) and a tapered rubber stopper from your local hardware store (can't think of the size off the top of my head)....drill a hole in the rubber stopper and insert a piece of metal tubing ( i used brass tubing) and you have the Ford Special Tool.

I have some rubber stopped too from when I had to chamfer the lip of my saleen intercooler reservoir - that's no prob

There is a SEARS by my place on the way home I am stopping at - hoping they have the vac (its listed online)

I thought I saw pics online of this process - you place the stopper in the open brake fluid reservoir in the engine bay, correct?
