Hi,

My brake master cylinder is leaking slightly, and i was just wondering what my options are rather than buying an OEM master cylinder. Nissan quoted me about $420 ex Japan. Are there any aftermarket manufacturers of these that people are aware of? Also, is it possible to have the cylinder reconditioned?

Also, is it possible to upgrade the master cylinder instead of buying a direct replacement? I mean, can you get a larger diameter bore that will reduce braking effort or something?

Its a 1993 R32 gtst M spec.

Thanks,

Shaun.

Yeah, thats what ill probably do.

I was just wondering if there was an upgrade i could do at the same time, but i discovered that ive got a 1 inch bore master cylinder which is pretty good for a gtst.

BM-50 is the code on the side for interests sake. Its the latest model r32 gtst which must have recieved an upgrade because the others are 15/16" i think.

Shaun.

if you want a replacement i have one here from a halfcut low km though

Does it have BM-50 on the side and does it have two outlets?

How much do you want for it?

RHD Japan just emailed me; US$150 delivered for a new one. Thats pretty good considering Nissan Australia want about $420.

Thanks,

Shaun.

Does anyone have an answer to the question of whether there is an alternative to OEM that is better? I to suspect i have a leaking master so would like to know.

i wouldnt change it because youd lose the pedal feel by doing a change to a larger one....

Am I right in saying that if I increase the piston area by upgrading calipers then a larger diameter master might be required or preferable?

yes thats correct

matching componentry is a must

my v spec has a factory 1 1/16 brake master on it because it has brembos where as normal gtr is 1 inch i think

I got mine rebuilt for $100 in Victoria.

They charge another $100 to remove/fit back on.

If you can do the removal/fitting then it will only set you back $100~ to replace seals etc

Hi Rekin. where abouts in Melbourne did you get it done?

300zx is the same size and will fit, and gtr will also fit.

I run a gtr cylinder on my 32 brakes (which surprisingly are basically the same as z32)

yes as long as you have abs... for people who dont know you do need to clarify sometimes

Yeah, please advise where you got that done. Cheers.

Yeah, i think my master cylinder is the same as a GTR one because its got a 1 inch bore (the number 1 is stamped on the side of it). Most other R32's seem to have a 15/16" bore in them. Mine is a 1993 M-Spec and has ABS if it makes any difference. It also has BM-50 on the side of it.

Can anyone help me with a Nissan part number for it? I can get one delivered from Japan (RHD Japan) for US$150 which is pretty good, but they need a part number.

Also, that rebuild for $100 must only be the seal kit and labour required to replace the seals. Everyone ive spoken to says that if the master cylinder bore is pitted and needs to be rebored (and have a stainless sleeve installed), it costs at least $150 just for the rebore. The cheapest ive been quoted is $240 for everything. If anyone knows otherwise, let me know.

Shaun, I've checked RHD's web this morning and they are quoting $420AUD landed for a new master cylinder........Coincidental number huh? When did you get the $150US price?

Yeah, i just discovered that they quoted me on a CLUTCH master cylinder, dammit. Thought i was onto something there!

The part number for the 15/16 brake master cylinder is: 46010-02U20

and the 1 inch is: 46010-04U20; maybe that will help someone, but im just going to get mine rebuilt.

Shaun.

    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
    • I assume clearances were all a-okay?
