hey guys

im looking at buying a set of 34 brembos for my gtr. ive done a search but theres so much shit i cant seam to find just the simple anwsers i need.

1. will i need to change the master cyl to cope with the biger pistons??

2. the fronts are just a matter of driling out the hole in the hub to 14mm??

3. my braided brake lines will just fit straight into the brembo cails and just a matter of bleading them??

theres more,

thats just all i can think of atm

cheers Deano :thumbsup:

I'm in the process of putting 34R V Spec2 brembos on my 32R.

For them to fit you can drill the hubs out to 14mm but it would probably be better if you just get some inserts installed on the caliper so that it is the same as your hubs. I forgot the size and thread type of the 32 hubs but I have it written down somewhere at home.

You can choose to keep your standard brake booster or go a 34R one. The 34 is bigger and will give you better brake feel. It will bolt on, the only difference being that the plug for the sensor on the 34r booster is different. This is easy to modify for it to work though.

Your 32 lines will fit straight onto the 34 calipers.

Remove your backing plates when you install your calipers.

Hope this helps.

Problem is they really are not "that" much bigger/better.

Certainly not for the price people want anyway. Putting better rotors/pads/fluid/lines onto the factory set-up would be significantly better than a 2nd hand set of Brembo's for around the same cost or less.

Pretty certain you can get a 330 (or 325)mm rotor under the Sumi's - Roy has posted a few times about it.

Just something to think over anyway :D

Cheers Nismoid I'll think about what u have said

Have a look at the UAS upgrade packages... They move the caliper (r32 or r34) out and use a larger rotor. Along with fluid and pad upgrades you'll be golden.

There's not much point just upgrading the calipers without larger rotors.

You may have to upgrade to a 34gtr master cylinder for the 34gtr front calipers... I believe (don't quote me) the 34 master cylinder bolts up.

Dont waste your time with R34 GTR calipers if you have an R32 GTR. The R34 caliper is from a performance perspective identical to the OE Brembos fitted to the R33 GTR and R33 GTR. SO why buy an R34 GTR caliper which requires you to mod your hubs when the R32 and R33 Brembo GTR caliper are identical and bolt on?

As for master cylinders, dont stress. Lets assume you have the Sumitomo R32 GTR master cylinder in your car. That means you have a 25.4mm master cylinder.

The Brembo spec GTR brakes are paired with a 26.9mm master cylinder, but unless your R32 has ABS it makes it pretty hard to retrofit on your R32.

There will be no difference if you just run your std master cylinder. If you ever have a failure of the master clinder then it could be worthwhile investigating installing the bigger master cylinder, but I dont think its needed to make the install work.

thanks Roy, ive got a brand new Master cylinder in my car, it was put in not to long ago. My car was NOT fitted with abs from factory as its a Nismo edition.

thanks for all the heads up guys ill look into the UAS kits too. im in no hurry as my brakes now have brand new AMR1 pads and Brand new RDA sloted rotors, braided lines and are all in good nick.

^^ Yeah.

I too was thinking about R34 GTR Brembos, but realised they are similar to the R32 and R33 GTR ones.

So Deano 1, I say you just find a set of R32 or R33 GTR Brembos and should just be a straight bolt on fit...

I am in the same situation, on the look out for R33 GTR Brembos.

      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.

      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).
