    Well, i recently installed a hydraulic clutch setup in my 83 Gmc pickup. I got a new master, and a new slave cylinder. I cannot get the clutch to bleed out all the way. I have free play about half way to the ground in the pedal. I've tried gravity bleeding it, bleeding it holding the slave at a 45 degree angle, bench bleeding, and pumping the hell out of the pedal. I also bought a mighty vac and tried it with that. I cannot figure it out. I just wanna get this thing bled so i can sell the truck. Any other hints or tips would be appreciated.

    The very first thing that needs to be adjusted is the pedal free travel. Once you have pedal free travel adjusted then you can continue on to bleeding the slave cylinder. Most people don't realize that you MUST block the clutch fork from moving in order to properly bleed a slave cylinder. Once the clutch fork is blocked with a piece of wood or other item so it cannot move then you can bleed it with ease. :thumb:

    Thanx! I was trying to figure out how to say it, I always used a prybay to hold the fork in place then had someone else hit the pedal.

    ok, i did that and then got just about a full clutch. I drove it around the block and it was perfect, then when i got back home i had a full pedal, but it wouldn't go in gear. :mad:

    You no doubt have air in the system still. Re-bleed it again and see what happens, just make sure that the clutch master never runs empty or near empty when you're trying to bleed it or that will allow air into the system.

    Thanks ALOT for the help. I was going crazy, luckily my head is shaved therefore no hair to pull out.

    ok, i've been bleeding it over and over once again. I cannot get a full pedal again. I'm real close to just paying somebody to fix it.
