R33 gtr brembos are direct bolt on to z32. IF r33 gtr brembos are bolt on to r33, then in theory the z32 caliper 'dogbone' adapters will fit r33 and enable 324mm rotors with stock calipers.

Early ones were alum, later ones iron.

Regardless, it's a simple and cheap mod for 324mm rotors, assuming the r33gtr calipers are bolt on to 33gtst as I said in my first post.

So why'd you get them??

If you actually do go to the track just make sure you put in some good fluid and it will be fine..it will take you a year of track days before you kill the brakes at least and that's if your a hack or very fast, they should last much longer if you drive clean

I'm not sure what the specific concern is about ADR approved brakes lines when the calipers, pads and discs, or how they work as part of a system, are also not ADR approved?

I think it is because it is easy to build a caliper that actually works without breaking open and leaking your fluid out while you're trying to stop. But there was a time when the first braided lines were being tried by people when there were inferior ways of swaging the ends on and so on that led to them failing. The ADR regs for how brake lines were to be constructed (or the tests they had to pass at least) already existed, so they just made it a requirement that any aftermarket ones had to be ADR approved. Not that the requirement wasn't already there in effect anyway, but at least if you require that they have a specific approval number granted by the regulatory body, you have an effecttive filter to stop the carppy ones being used.

Sure, there may be good ones available that don't have approval, and it sucks to be them. But they could always get them approved and start selling in competition to those that already are approved. But, to recoup the cost of getting them approved they'd probably come out at the same price anyway, so you wouldn't have the situation like those cheapies on the eBay link being as cheap as they are.

Thought Ill give them a shot, im not going to be doing alot of track work, mainly just deca, haunted hills type stuff so I think these will be fine.

Definently will put good fluid in, will also do brake stopper and braided lines.

I personally wouldn't trust any brake line from overseas or that isn't adr approved, I guess if its adr approved theres less chance of a failure. I've seen a few jap branded braided lines burst but never a Hel one.

    • 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       
    • 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).
