Question for ATS boys....

[Van B]

or anyone else with a good answer.

I am having one hell of a time trying to bleed my clutch. LS1 era T56 running a Spec Stage 3 clutch. My master and slave were dry when I started. I tried having someone work the pedal while I opened and closed the bleeder, but had limited results. When I finally get some "feel" in the pedal, it still will not disengage the clutch.

I have looked all over LS1 Tech and read about everything from opening the bleeder and letting it gravity bleed to sucking air out with a mityvac.

I am lost. Any input is appreciated.

You will probably have to remove the master and hold it level or tilted upwards. I removed my hydraulic unit and bled it by hand. That's what worked for me. I think if it is installed you have to back feed it not power-bleed. FRANK

Usually it will bleed on its own but it does happen.

Very common to have a master fail if left dry for very long.

One thing to try is remove the line from the slave inlet,(a job in itself sometimes) put your finger over the end of the hose and have someone SLOWLY push the pedal down while allowing the fluid to leak out, when the pedal is all the way down then apply more pressure with you finger on the hose end to seal it as the pedal is raised. Repete several times till fluid flows constantly.
Reinstall the hose then let it bleed on its own. Pump very slow. A fast pump will cause cavitation.
It should come back, if not be ready to replace the unit. $47 at GM parts direct.

Jeff-
I know we talked on the phone, but I thought I'd put this here for others if they have trouble bleeding an LSX master.

I take the head of a roofing nail, and insert it into the plunger in the quick disconnect at the end of the master cylinder braided line. I then keep the reservior above the entire assembly, and pour brake fluid through to gravity bleed it.

After you have gotten the master filled, take the nail out of the plunger, install it back into the car, connect it all, and bleed like a brake system- Pump a few times, while someone under the cracks the bleeder until no more air is released.

I'm curious to see if you get it solved, so let me know after you've given it a try.

I will let you know. I may not get to it until Saturday, but I am itching to drive this thing.

I'm a big believer in Motive Products bleeders. I bled my brakes and clutch from dry to done in less than 10 minutes each.

Just fill the master reservoir, connect the pressure cap from the bleeder, pump to 10 psi, then release the bleed screw. Watch the level in the reservoir, and add fluid as needed. It's just too damned easy. I didn't pre-bleed anything, and I've no problems with air in any of my lines.

New hydraulic master did the trick. The car moves under its own power now. It was cold and rainy this morning, but when I started it up, pushed in the clutch and it actually slipped into first without creeping, I couldn't resist taking it down the road. That is a good feeling.

Big thanks to Tyler!
