hey all..

recentlly put r33gtst front rotors (redrilled to 4 stud) and calipers onto my a31 cef.

still get standard back brakes.

now the pedal feels a bit spongy compared to full standard setup.

my question is will r33gtst brake master and booster cyclinder rectifiy this spongy pedal problem??

the lines need to be modified slightly to work with this master yeah??

searched but couldnt find exact answer to my dilema.

cheers lads :)

More likely it's BM38 - standard 7/8" BMC. R33 gtst uses BM44, which has 15/16" bore. Changing BMC is unlikely to fix spongy pedal, as it is usually something else that causes that spongy feeling, but it will reduce pedal travel and increase force required to be applied by your foot. If that is what you're after, then by all means do it.

Nah, sorry man, IDK for sure, but I _think_ it may be bolt on, as AFAIK A31 chassis is pretty close to R32, so line routing should be similar. 

If you post a pic of your BMC I'm sure people here can say if it's bolt on or not by the looks of it. 

Make sure you get yourself correct BMC though, i.e. the one suitable for ABS if you have anti-locking brakes (with two outlets), and non-ABS otherwise.

      R32 GTR EV? The leaf of the Godzilla's!

      Somehow Vertimass/Oak Ridge National Labs has figured out a catalyst that can convert ethanol into C9-C10 hydrocarbons in basically a single step without ending up with a bunch of ethylene or similar waste products: https://patents.google.com/patent/WO2023224867A1/en I still don't think anything like this will keep us from needing to transition to EVs regardless along with all kinds of other electrification, but things like this will go a long way towards alleviating the problem of how to electrify things like planes. Renewable diesel is seemingly an easier problem as well, Chevron is already running refineries for the stuff and the primary feedstock is tallow and other waste fats from agriculture.

      Ok so I have sorted everything with my uniclutch and  i can offer up a bit of feedback and some things that might help others.    I found problems with factory damper line. Weird shit and had trouble with peddle adjustment    I used this https://au.gktech.com/products/r33-gts-t-skyline-braided-clutch-line?_pos=2&_sid=22b01b9b9&_ss=r Also when adjusting peddle leave a bit of play. You can get into a over stroke condition easy.. Make sure you can push the slave forward after adjusting to confirm fluid can return to master then you will need to pump it up heaps…..not sure why but that’s how it is.    last thing the splined adapter is machined perfectly. If your input shaft is old like mine was I would put a bit of valve grinding paste on it and stroke it like a 15 year old. Just to give it a tad more clearance and to better match it to the spline.    reason is on a near flat shift I have had situation where the peddle returns a millisecond after you lift from the clutch. No slip or anything but I reckon this is due to tolerance on the spline being way tighter than stock clutch and binding for a sec. I think this will go away but also my spline was old. Box is old so I guess I should have checked better. It’s a super neat fit.    it feels light as and holds awesome without any noise

      Was that Australia Delivered Duncan? Does it have siren etc?   I used to have remote start on an old 32 two decades ago, it was a cool feature. I used to wake up early in winter for work. Start it and by the time i was out the door a few minutes later the engine was warmed up and the heaters had the car toasty. It was great.    I don’t mine the ambience lighting.  I drive a western star and it has footwell lights and ambient lighting and it’s great! From the pics of seen of them installed in a skyline I think it’s a nice touch
