Hey all,

I've got a R32 GTR and just had my HKS Twin Plate clutch rebuilt and installed.

Picked up the car last night... go to take off and the clutch's pick up point is right on the floor... like I move my foot a millimetre and can feel the gears engaging.

OK, that's shit... but I can get used to that.

The gears were much tighter but the whole transmission seemed pretty smooth right at first.

As I'm driving it home (driving it easy and not loading up the clutch at all due to the bedding in period), it seems as though as the car is getting hotter the synchro or hydraulics or something is having issues.

First it started not going into 1st gear, so I'd have to put it in 2nd and then shift straight to first... I thought, weird, as the box has never done that before.

Then it started to feel like I was running out of pedal and would have the clutch all the way in but I could tell it wasn't fully disengaging the gears and the revs would drop down due to there still being some contact.

Then on up-shifts into 4th, I could feel the gears hitting and not meshing properly.

Then this started happening in almost every up-shift and was a rough hit of the gears on the way in due to the lack of meshing and sometime would just mash and not go in.

Then the pedal got even lower and I couldn't get it out of gear without slamming it out and there was no way of getting it back into gear (tried all 6 and it was just mash mash mashing - praying I didn't do damage to the box as I was getting a little frantic at this point).

Turned it off, let it cool down, and then I could get it into gear again. Not very easily though.

But, drove it to work this morning and I had to double clutch on every down-shift to get it into gear without mashing, and by the time I got to work, even with double clutching, I could barely get it into first!

Please help...?!

I'm destroying my gearbox at this rate (going straight back to the shop tomorrow morning), but I really hope not too much damage has happened so far...?!

hi mate, i had the same problem with an older car i had, the friction point slowly moves closer and closer to the floor.

turned out to be my slave cylinder had a hole in the seal and wasnt holding enough pressure for the clutch to disengage.

had to rebuild the slave cylinder only cost about 30$ for the kit, and took about an hr from bonnet up to bonnet down

however it could also be the master cylinder,

or even the mechanic just didnt bleed in the clutch proply when he put it in.

      @soviet_merlin Thanks mate!  Nothing too major but will hold me up for a while. I've got lymphomas to get taken off the back of my neck and the middle of my spine which always conjures scary thoughts!  It sounds worse than it is. Yeah great, conjuring more rabbit hole deepening , just what I need! 🤣

      I'd argue the F50 kit I got is very good value. For ~2k I got the calipers (refurbed condition), adapters, pads, brake lines, rotors, and top hats. I think you'd be pretty hard to get Evo/GTR/350z brembos + the additional hardware for similar money. Used market for a pair of front calipers alone I've seen tend to run anywhere from $1500-2000 depending on condition.    That said, something like a GTR or 350z brembo is a lot easier to adapt to the Silvia.

      Is there a significant price difference between the Evo/gtr/350z brembos vs the F50? Looks amazing.

      I was actually being a tightarse at the time LOL... My OCD is tickling me into running a 2nd 8AN Teflon hose all the way down and removing the 2x OEM hardlines. My other side of my brain is telling me to run 2x hardlines front to back (also acts as a fuel cooler, so win win).

      As I mentioned in an earlier post, I had some trouble with the Silvia's brakes dragging back in 2023. I managed to sort it out then, but the same problem came back to bite me late last year. Just take a look at the picture – I had a feeling the handbrake was acting up again, and I was right. Anyway, I'd been wanting to upgrade to bigger brakes for a while. Not that the Silvia's brakes were bad, but it was more of a "want" than a "need", you know? It was funny, though – at the time, I couldn't find any Evo Brembos, 350Z Brembos, or GTR Brembos for a decent price (of course, tons of them popped up online after I already bought my kit!). I ended up going with an F50 Brembo kit, which came with adapters, brake lines, 330mm rotors, and top hats. The F50 Brembo caliper was used in a few other cars too, like the FPV. I also decided this was the perfect opportunity to ditch the Silvia's ridiculous rear brakes and that awful handbrake (some of you were definitely right about that!). I picked up some R33 calipers and all the necessary bits – rear drums, backing plates, and new hardware to refurbish the calipers. Of course, it wouldn't be a project without a few hiccups. Turns out the brake master cylinder was playing up and basically (to put it simply) keeping the brakes engaged. I had it overhauled, and after some adjustments, everything was working again. The whole process took a while, as you can imagine. To top it off, the front right wheel bearings were shot and needed replacing too. This is a rare occasion where I'm posting an update while it's all still fresh! These pictures were taken just this afternoon.
