Hello  Everyone,

After fully forging and building my r34 2 door rb25de neo to a turbo conversion...  i would like to do a brake disc and caliper upgrade.

I know for sure for sure for sure there IS a thread  somewhere that i read a couple weeks ago but i just spent a hour looking for it and no luck.

My question is, can i buy brake discs and calipers upgrades for a r34 GTT coupe? (cant find aftermarket shit for the NA r34)

i think i heard something like the N/A brakes on the r34 is actually r33 gtst brakes and discs.

If anyone can give me some advice or even direct me to a thread it will be greatly appreciated!!

Yes. What I can't remember is if they'd given up on 4 stud wheels on the NA by the time they got to the R34. If you have 4 stud, then it is a lot more work and stuff you need to get - because the turbo stuff is obviously 5 stud.

Nope.

NA R34s were still sliding caliper junk. R33 GTST are 4 pot Sumitomo on 296mm x 30mm rotors.

 

There's a lot more than one thread covering this stuff on these forums. Use google to search the forums. You will get much better results.

Mate, you are not searching hard enough or not reading the entire threads. Try this on this forum

if you want cheap Brembos and don't want to pay the GT-R tax, get yourself 350Z Brembos calipers, Rotors :)

They will sit a bit future out compared to the GT-R ones, but if you've already got some decent wheels you'll clear it.

Oh, here's a guide I wrote many years ago:

I'm also not sure if the R34 NAs went to the 14mm caliper bolts like the turbos did. If they are still at 12mm, then fitting R34 turbo calipers requires changing the threaded inserts in the calipers.

If the NAs are 12mm, the you could fit R33 calipers easily enough (on the 296mm rotor) or you could fit R32 calipers (preferably using a dogbone to push them out so you can use the 324mm rotor - which you CANNOT do nicely with the R33 caliper).

The info on 12/14mm is available on here. I just can't remember.

Habib, if you read the guide it will make sense.

No thread inserts, those are gay.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
