Rebuilt slave now clutch is slipping (Page 1/2)
cvxjet NOV 23, 02:30 PM
I had my slave cylinder fail and then rebuilt the RD slave with an RD kit....Bleeding took some time- and then after a week of driving it I started to realize my clutch is slipping under hard accel...

Any suggestions of what the problem may be? (Note; The Ram HD clutch is not that old- maybe 5 years and 10,000 miles) (3.4 F-body long block conversion and Getrag 5 speed)

Almost sounds like the master cylinder is not allowing the slave to go all the way back or something in the slave is not allowing full return. Just a couple of things to check. try opening the bleeder and see if the slave moves back which would indicate the master is at fault. sleek

Just checked and the slave is under pressure- (I looked and noone was pushing the clutch peddle....)

I had no problems with the system and then the slave failed- rebuilt the slave and now it is under pressure.....why would the master go bad at the same time? (Basically)

Interesting. Does the clutch pedal (not peddle!) fully return to its "rest" position, or is it down a bit?

HI again. I would check the master with the line disconnected at the master to make sure it will return all the way.If it will then i would suspect that maybe the line is plugged from dirt ,rust or collapsing line.
Possibly the line or master caused the problem with the slave. don't let any fluid touch paintwork as it is very good paint stripper. sleek

A) The clutch peddle is fully returning to it's up/back position. And I have checked the line and no crushing or pinching...When I bled the system I bled the heck out of it- both pumping and used a vacuum tool to pull fluid thru...flowed well/easily.

B) I used to do HazMat for the Coast Guard air station at SFO....Kept having guys dump brake fluid in the waste oil drum- finally put a sign on it; "Brake Fluid goes in Waste PAINT drum" and had few problems after that.

Is it the banjo connected to the master that is pushing the pedal back up, or do you still have the clutch pedal return spring in place (which Pontiac stated should be removed)?

I'm just trying to figure out how the clutch pedal is able to return all the way back up if the master is indeed still somehow exerting pressure on the slave. I'm not suggesting that this has been misdiagnosed (not at all!)... I'm just curious how this is all occurring.

The return spring on the peddle is what is pushing it back/up......the Slave is completely stuck- no fluid will flow back- don't know if it's the slave or the line that is blocked. The clutch is toast- I thought it was slipping and started the engine after a week to let it run for 15 minutes- when I shut it off I thought I smelled something but not sure. A few hours later the garage still stunk- burned up the TOB....(Arrgggggg)

To get the line off the Slave, I have to fight a rounded off hydraulic nut.

If you opened/removed the bleeder on the slave and it still doesn't release, then it would appear that the slave piston has become stuck/seized in the bore.

I opened the bleeder and it spurted fluid.....now have the slave off and will disassemble it to see if anything is blocking the "Line in" hole...Then I have to remove the Master and examine it- last is running a snake thru the line- not sure about how to do that (What diameter is the inside of the clutch line?)
