But I'm stumped. About a week ago Lucy's clutch hydraulics gave-up on me, so I replaced both master and slave cylinders. However, I'm having trouble bleeding the thing. I've got the circuit assembled on the bench and tried to bleed it. Opne slave bleeder, push master piston, close bleeder, release master piston. However, no fluid gets sucked in front of the master piston. Open the bleeder back-up and it sucks air back in. (piston returned without drawing fluid in).

Now, the master won't even bench bleed properly, should I return the part and get another? Or am I doing something wrong?

Thanks for the time, sorry if this is really basic.

 

try bench bleeding the master into itself, to prime the system, then hook up the slave and bleed as a unit.
i usually just bolt it all on the car and hookup a vacuum bleeder to the slave and moniter the fluid in the master.

You can always try one of those "one man" brake bleeding kits.They work good.
and try this..Push in master,then Open bleeder,it will spit,then close bleeder,repeat.That should get the air out.

 

are you sure your bench bleeding it corectly? make sure once you bench bleed it not to let the master run dry before you get the lines attached or you defeat the pourpose. just a thought

 

do this
take a clear water bottle, fill 1/4 with clean clutch fluid, attach the hose to the slave bleeder nipple, and have the other end in the fluid. open the bleeder and just bleed away.
itd better to do all this installed in the car

Sorry, I completely forgot about this thread until recently. I guess my bench bleeding apparatus didn't have a complete seal, I hooked-up the circuit and tightened the fittings down...viola!

That aside, with the new master and slave, the clutch releases fully now! Before, trying to drop the clutch or shifting hard would slip the clutch. Now...I can peel-out! (heeheeheehee) My instructors at CC think that oxidation built-up at the base of the slave over time (the fluid was horribly filthy) and stopped the piston going back all the way. Plus, the clutch pedal is so high and firm now.
