Help Clutch Gone!

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

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

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.

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 pinch.gif

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

      Duncan's V37.......race car?

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
