Yeah same as normal rears mate.

You sure?

DBA list the povvo pack R32 GT-R rears as 297 dia x 18 thick. The R33 & R32 Vspec are 300 dia & 22 thick.

The other thing you need to do when bolting up a Brembo rear to a non Vspec R32 is bash the stone guard to get it out the way. The bit near the hub fouls so bash it gently - with a hammer.

Or just grind the stone guard off completely.

A few things about the rears that I discovered doing the conversion:

The inner pads wear like a bastard if you don't remove the stone guard.

The upper outer link on the rear suspension is pretty close to the guard so be a bit carefull that you don't get too much heat onto the bushes. I taped mine over with some metallic tape so help reflect the heat.

The guard (from memory) hooks in under the hand brake shoes so you can't remove all of it.

Oh and the hoses from the R33 are too short for the 32's.

But you can use the lines from the R32, you also need to make sure you have the bolts off the R33 as they are a different pitch to the R32 caliper. Get rid of the shield all together, its not that hard, you just need to drill out the spot welds or just tin snip and rip back and forth until the spot weld rips. Then just file off any sharp edges.

You can even use the std brackets etc with a small 10min tweak per bracket. (i run aftermaket braided lines on my R32 before upgrading to the GTR rears, so should point out that my aftermarket R32 braided lines worked perfectly with the GTR Brembo rears)

I am trying to remember why my 32 lines did not fit (or seem to fit). They were a bit different. It was easier for me in the end to get some new lines seeing as I upgraded everything else.

The Brembo bots are 1.5mm pitch, the Sumitomos are 1.25mm like most of the other Nissan stuff.

Shit! I may have been wrong it seems re the rear rotors, my sincere apologies mate, my old memory is failing as I just couldn't remember changing the rear rotors when I put brembos all round on my 32 GTS.

Sorry again. Oopsy!

      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).
