Your clutch booster is probably fubar! This happened to mine, I always had a really heavy clutch pedal, then I discovered someone had put a bolt in the big rubber pipe that comes off the drivers end of the plenum, I thought wtf! So took it out, clutch felt great while idling, but driving it was a nightmare, one minute it would be a really nice smooth, lightweight clutch, the next it'd be all heavy again and grainy/crunchy too. Did a pressure test and sure enough the booster was fubar, so now the big rubber pipe is cut in half with a bolt out of the end of it, until I put an NA balance bar on.

Have you got all the metal work still and the bleed valve up in the engine bay? there is two if you have the OEM set up, one in the engine bay the other on the slave cylinder. why you are trying to bleed the clutch at the pedal is beyond me.

 

You need to bleed the cylinder first then the top bleed in the bay.

car used to be an auto but now a manual, not bleeding at the pedal but pumping the pedal to get a pedal. using the slave as a bleeding point. will have a look at the clutch booster cheers.

just remember its not like brakes the pedal wont go hard, but what you want to do is have some one putting in the clutch fluid into the res and bleed the system till no more air comes out, then do the nipple up, thats it.

 

if you have straight through pipe from res to slave, it should be easy as hell to bleed.

clutch fork new? what about the clutch bearing, pivot ball? and clutch fork split pin?

Hi mate cant be anything to do with bleeding, if you took the slave off completely and put it in gear, then it would be in gear,It would not make the clutch slip.

 

The slave is for when you put your foot on pedal takes it out of gear,

 

Slipping must be worn centre plate, Or maybe something on the clutch fork,

Was the clutch kit new.

 

Good luck mate.

 

Sorry just seen its new all new, Are you sure you aint bent the centre plate, does it go in gear with foot on clutch pedal.

Or is their no pedal at all.

Have you checked the clutch pedal rod adjustment, if over adjusted it will be preloading the pressure plate.

Why do you think bleeding will fix a slipping clutch ?

i dont think its bleeding thats your problem, i feel you need to remove the gearbox to find out what the issue is.

As Jeff said, it sounds like you need to adjust the pedal. If the length of the rod is out it really does give you problems.

 

I had the same on mine when I converted but once I fixed the pedal throw it was much better.

tried bleeding tonight and tried for a good while and no joy, got a litle pressure in the pedal not alot then lost it when car was started, going to check the adjustment when light its a ashame when i put the clutch in was fine for a 100miles then started to slip badly, when i took the old clutch out for the same reason it seemed to have loads of meat left on it:-( just want to get it sorted now.

I know you shouldnt really do it but if you remove the slave off the box completley and put car in 1st gear and turn the key it will jump off and go, if you then touch the throttle and it starts to slip,

 

then its something in the box,

 

if you dont fancy doing the above, while someone is pushing the pedal, get down by the slave and see what its doing, try pushing the fork back while somebody is pumping the pedal and feel if it has any movement, maybe theirs something on the pressure plate gone wrong and fork is pushing to far forward while trying to bleed it.

 

I may be wrong but if pressure plate aint pushing fork back properly your pedal aint gonna come back properly.

 

I would say its a problem in the box, centre plate, pressure plate or fork problem.

 

 

Goodluck mate.

See i know all these cars are differant but i converted mine to manual and used a pipe from master to slave, (seems like you have too)

And it has never been a problem to bleed.

 

Have you tried undoing bleed nipple on slave and filling up master cylinder and pumping with nipple undone, what i sometimes do on brakes is put my finger over bleed nipple when they lift up pedal and seems like it causes a suction and pulls fluid through.

 

Had a prelude few years back and it was a bit of a pig, the brake master went, so i got another and couldnt get it to pump straight the way i think wedged pedal down left it half hour with nipples open,

 

And it was good after that.
