So i was bleeding the clutch, which I have done before successfully but this time I may have let the level in the MC resevoir get too low. I think I sucked in a big pocket of air, because when I was done the pedal works but is spongey, and engages just off the floor. I have bled and bled and there is no air coming out. All of the threads I read state "don't let that level get too low", WELL, what happens if you do and how does one fix it?

 

The master cylinder sucks in air and you get to spend lots of time bleeding it out.

 

If it gets too low you get air in the system. Kinda ironic that it should happen when bleeding.

If it is really bad you should just keep bleeding and making sure there is fluid in the res.

 

I've found the best way to get all the air out is jack the back of the car up so that the bleeder screw is the highest point.

 

Billman250 has a nice method developed, remove the slave cylinder from the trans, tip the cylinder to put the bleed screw at the top, then crack the screw loose to remove the air. Reinstall the slave cylinder, making sure the pushrod is seated in the clutch fork correctly.

 

what if you are using a ap1 slave on ap2.. its doesnt really sit flush. so i didnt use the forks i just turned it side ways. ???

 

Same process on both style slave cylinders.

 

so take the slave cyl off the tranny (IIRC it is held on by two bolts), and tip it so the bleed screw is at the top, then bleed the same way? I can't really see how this would help me unless the air was trapped in that small rubber hose right at the slave cylinder.

 

sometime the bubble just don't want to come out, it happens all the time.

i never took the slave out and it works fine, i think if you know what you doing, you are fine, by experience you can tell how much air you should see.

a series of rapid strokes always does the trick for the clutch bleed for me
