REAR KIT UPDATE Just thought I would update on what we are doing with the rear as the handbrake is causing this to be a pain in the ass. Basically here's what I have found: The option with having th

The booster doesn't get changed.

The master cylinder can be changed to get a better pedal feel but it's not required. Basically the amount of fluid displaced at the master cylinder is equal to the fluid displaced at the calipers, so by making the calipers fluid capacity larger (larger pistons etc) you will require more pedal travel to displace the pistons the same amount.

You don't have to go out and buy the BM57 master cylinder, you could also try re-boring your existing one. Try a brake mob like Slacks creek brake and clutch if you are in Brisbane

The calipers appear to be 151.2mm wide. I just measured the stock calipers on my car and appears to be about the same.

Here's the measurements I used (the first picture):

Hey Phil,

Again I see that you seem to be buying the same gear that I run on my car.

I've been running the Superlight 6 piston Wilwoods on the front of my car for over a year now, and yes they fit under my 17" rims. I purchased my kit through Arizona Z Car in the US, and I believe you'll get a better deal if you go through them. Contact Dave and see what price he can do for you without the brake lines, the link for his site is: http://www.arizonazcar.com/

I did upgrade my master cylinder to a 1" item from the R32 N1 GTR (non ABS) but as you've worked out, the upgrade isn't necessarily required.

Hope that helps, Ryno

You'll also see that Dave's kit runs even thicker rotors (at 35mm) and the alloy hats are a different design.

Awesome quality though, so I've been very happy with the purchase.

All up they came in at about the same weight as the stock R33 calipers and discs, which is a pretty impressive feat given the size increase.

Ahh nice :)

Yeah I looked into the Arizona Z kits; they use slightly different 6 piston calipers and as you have said their own rotors and hats. I might speak to them regarding the rear kit when time comes as they make their own single piston caliper kit for the hand brake setup.

I use my car for street driving, but the Arizona Z Car package has been designed for the track, just have a read of some of the testimonials on the site.

When I bedded in the pads, after the 10th hard stop in a row from 110 kph, it was still wanting to lock the front tires, with no noticeable fade.

Yeah that's the one.

So in doing this phil does that mean we would be able to ditch our stock drum handbrake setup?

But also wilwood make 2 rear superlite caliper kits, 1 with an internal handbrake setup which would allow u's to do the same thing and delete the drum setup, or the other option which doesn't have a handbrake setup?? I thought it would just be easier to keep it as 1 system? Correct me if I'm wrong.

If we can get a 4 piston caliper for the rear with a built in hand brake into the caliper than that is definetely the way to go. Yes it will completely get rid of the internal brake shoes for the handbrake.

I came across this a while ago, however it mentions it is for light vehicles.

I will have to discuss it with the supplier and see if they make something that will suit our application.

      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.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      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).
