Help Clutch Gone!

[tobs_r32]

Hey all the clutch on my R32 GTS-T just died out on the way home the clutch itself is probably 9 months old and has never been driven hard. It basically lost all pressure in the pedal and wasn't springing back from the floor, the weirdest thing is that i had a brand new Master cylinder and a second hand working Slave installed only a month ago and properly bled up all professionally!! It seems to have dropped a small amount of fluid but the reservoir was still above empty, we attempted filling it up and bleeding on the side of the road for about 15 mins to no avail.

Does anyone seem to know what this may be or at least a general idea on what i should look at fixing? I'm going to have a decent look tomorrow to check for leaking or split lines but I doubt i'm going to be able to tell where the problem lies.

Cheers any help would be great

Check the clutch fork hasn't broken the ball thingy it swings on , other than that i'd be checking the slave cyl

Yeah thinking the slave cylinder too, but nick shaw seems to think that one shouldn't have died, would the fork pivot ball cause the pedal to stick like that too? it has about 4mm of pressure when we were trying to bleed it up but not enough to get into gears or anything!! Cheers for the help man

Get somone to watch the slave cylinder while you puch the pedal in, and see if the ram is going in and out.

Yeah turns out the slave cylinder has shat itself and caused the pivot ball to break also!!! Gahhhhhhh and after only getting everything replaced 3 weeks ago so much money and I look after the car so well!

Its good that you've figured it out mate, are you sure the slave cylinder is broken? as the slave cylinder failing wont cause the pivot ball to break, did the clutch pedal go really stiff when it broke or did the pedal just drop to the floor under normal conditions ? The hub that the release bearing is on may have gotten dry and sticky or could have even jammed causing more load on the pivot ball/clutch fork, let me know if you need any bits mate as i have a few gearboxes laying around.

was your new clutch a heavy duty one?

they tent to shatter the pivot ball

[toffy]

i would say the pivot ball broke first causing the slave to hyper extend , the usual cause is from not being cleaned/re greased on clutch changes (if the clutch feels un-usually heavy , normally it's caused by this also) . the slave may be fine if you push the piston back in the chamber , there isn't much that can go wrong with them

Pretty simple little units, generally they just seize or wear/tear the seals.

Ok i brought a new one just to be safe and got a brand new nismo reinforced ball pretty cheap so hopefully i'll never see this problem again Thanks for the help!

DanielH did you end up finding that 32 gauge cluster at all mate?

[DanielH]
