I have R33 GTR brakes on my GTS-T, but we never changed the master cylinder to a BM57.

Now it seems I have a little leak in my seals so I'll get the GTR master cylinder fitted.

We've also noticed the GTR booster is bigger then GTS-T.

Is it worth changing this too ?

Looking at the clutch master cylinder, it's very close already and may have to be moved.

Anyone know if the GTR booster will go in GTS-T without dramas.

cheers

Why get a GTR master unless you were unhappy with the travel/feel of the GTST one?

I thought travel/feel is more booster related anyway ?

And master cylinder more related to stopping quicker.

I may be wrong, don't know.

Can anyone please tell me what to expect with the larger diameter booster, or is it a waste of time and money.

cheers

BM 50 will shorten up the pedal a bit if you can't find a BM57. Larger diameter shortens the pedal but increases the effort required so if you fit a bigger booster as well it may be a help.

Yeah I've bought a brand new BM57.

You reckon pedal effort will increase without bigger booster ?

Well it should in theory but maybe not enough to be a problem. I have been using the stock BM50 M/C with GTT brakes but have just got some 330mm 8 pot D2s (AP copies) for the front so I am looking for a BM57 m/c. If it deosn't come with a booster will see how my present one works. Let us know how you find it!

Kudos Motorsport in the Gold Coast have new ones in stock. $467 + $30 del. Master alone.

There's a wrecker in Greenacre, has an old one for $200 in fair condition.

I reckon parts will become very hard to get soon after what Japans been through.

You can order recon kits for the BM57 but right now it's a 12 week wait. The kits are $260.

Then you have to pay for a specialist on top to hone and fit.

Luckily I just picked up a genuine Nissan repair kit for $25 a couple of days ago! Second hand m/c go for $80 to $100 and usually come with the booster but the booster from my Stagea which was originally an auto may do the job. Everything's cheaper in the promised land although we don't earn as much as you Aussies!

I have a r33 gtst with gtr brakes all round and I was not happy with the factory feel so I fitted a Nissan patrol master cyl, these are larger than the gtr one and do not have a bias valve in them. This way I could fit a in line bias valve and dial in what ever I wanted. I have been using it for three years or so now and I am very happy with it.

howd this end up all working. i have GTR brakes all round on my BM44 abs equipped r33 gtst s2 and not overly happy with the pedal feel after install

Pedal feel is nearly always a sign that you need still more bleeding (supposing that you have renewed the fluid preferably with something like Motul RBF600).

Josh, when i had the brembos on my 34 i also had a spongy peddle, i used a bm57 to. Only thing i didnt change was the air separator the comes off the booster and plumbs back into the engine. Try finding one of them as all GTR's have them.

Luke, what does this thing do? You said it's a separator, so it separates vacuum? air? from what?

And I don't think it would feel any less spongy with this thing on.

Boz22n, what diameter BMC did you end up using? What bias adjuster? Ever had any troubles with adjustment range being insufficient, i.e. too much/not enough front/rear bias?

      R32 update from 1990's spec.

      By djr81 · Posted

      New CAS just turned up from NZ Wiring. Looks like a nice bit of gear.  So, yeah. Triggered, bro. Realised I may as well do the cam belt while mucking about with it so will order one of them.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

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

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.
