Hi sorry if someone has asked this before..I had a search :(

 

Just wanted to know if front brembo r34 gtr calipers direct fit onto gtt rotors with no issues..

My r34 came with front gold brembos and looking to change the worn down slotted rotors that it came with though im not sure if they are gtt rotors or a little larger or thicker?..thanx

Thanks I better do that..was seeing if anyone knew before i jacked it up..  was thinking it must be thicker then a gtt rotor...  though does a larger rotor fit?..  it would only be the thickness difference? Not a height or width difference?..   when I spin the wheel it sounds like the rotor makes a small grind sound when I try spin it..is this normal? Or shouldit free spin with no small grind sound?   ..sux when you get a car and not sure what someone has done or if it's riggt

No. GT-T rotors are only 310mm diameter. GTR Brembo rotors are 324mm diameter. You cannot put a GTR Brembo on a 310mm rotor.

Just repetition for repetition's sake.

 

But.....GTR Brembo rotors aren't thicker. They're all 30mm. Only the 296mm GTR rotors are 32mm. Right?

Correct for the R32 GT-R (non V-Spec, Sumitomo calipers) but some just throw on R33 GTS-t rotors as they're a bee's dick cheaper.

Are you sure they are R34 GTR calipers? It is very common to install Z33 front Brembo calipers but the rears don't fit.

If you have front a rear Brembos then they would most likely be R34  GTR ones. And the rotors are different between 

BNR34 and Z33.

R32-R34 GTR 324mm rotors are all the same

The Z33 324mm rotors have a different hat height.

You'll need to measure this to work out what you have. Google how to measure rotor hat height and follow instructions.

Ahh I'll look...they are the nice gold brembo that the had did z33 have gold?...crZy so z33 calpiers bolt dorr direct into the front if a r34? The bolt pattern to take them on and off...  thanks all I'll measure the height and all and see what size... they seem to take r34 gtr pads though looked up and z33 seems to have the same front pad.. so may be z33 brembos..

Thanx for the help guys..didn't want to buy the wrong one and have my wheels on And of alot..

My dust pan is still on my fronts and has the lip sitll..does this mean mine are r34 brembos and gtr rotors? As my dust pan is not hiting my rotor and has the lip..?..  in this guide for z33 calpiers you need to trim the dust pan lip or remove it for z33 rotors

      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).
