I just installed new master cylinder, slave cylinder, and flex hose. How the hell do I get fluid through the lines so that i can actually bleed the air out of the fluid. Cause i'm pretty sure there is none in the line. Since there is no pressure in the system, the clutch pedal springs to the floor, and that can't make too much pressure to draw fluid out of the reservior.

 

I would go to the auto parts store and buy a vacuum bleeder or do what I did and make your own pressure bleeder. Not only would it solve your problem, but it makes bleeding clutches and brakes much easier for the next time.

Otherwise, if you keep bleeding like you normally would, I think it would eventually draw fluid, but I'm not sure. I've always had a vacuum or pressure bleeder.

 

How much do vacuum bleeders cost? Would there be a way to use engine vacuum to draw fluid? I have a plastic canister, hose from the bleeder goes into the top, then in the container there's a short tube going to the bottom of the canister. Then on top of the canister is a hole where you could attach a vacuum line. Would that be smart or dumb? If you were careful, the vacuum line would not suck any fluid into it, right?

 

I wouldn't do it. A vacuum bleeder kit only costs $20-30. I made my own pressure bleeder with parts from Home Depot for about $20.

 

I put some hose over the end of the bleeder screw on the clutch and ran it up to a bottle, loosen the nut, press to the floor, tighten, pull clutch back up, loosen nut, push to the floor, tighten, pull back up, eventually it will start returning on its own when you let off, and shortly after that the fluid in the clear tubing ran solid with no air, then tightened and I was done. Don't let off the pedal until the screw is tight, or you'll suck air back into the slave cylinder.

 

Pretty much sums it up.
