Hello,

I've done some researching on this site that has been helpful so far.

I understand that Z32 / R32 front brakes are a direct bolt on to S1 Stagea. There's an orifice of sorts you need to remove.

I found that they fit perfectly on my S1, just had to remove a little orifice from the fluid inlet and I was able to use my standard brake lines with banjo bolt,

stock stagea brake lines bolt into the fittings, if you remove the flare fitting from the caliper, but are a bit to short and the lines are pulled too tight once fitted, so get a set of new custom length lines or braided lines.

So an orifice on the calipers themselves. I have reproduction Z32 calipers already in storage.

Honestly I have no problems just keeping the stock front brake lines and removing the orifice and throwing on Z32 calipers / rotors / pads. Cheap, cheap upgrade.

But if I can find some braided lines for less than the cost of the calipers, I would be interested. And if I get the right braided lines I wouldn't need to remove the orifice from the calipers right?

Great, product also works from going from C34 Stagea RWD to Skyline brakes

So RWD C34 and AWD Stagea front brake lines are different according to that and those wouldn't work. Or maybe they would?

R33 GTS-T braided lines - https://us.gktech.com/r33-gts-t-braided-brake-lines

But those are almost as much as the calipers cost me so I'd probably just keep the stock ones.

Can someone enlighten me?

I can't answer the exact question, but.... custom braided lines are not hard to organise. I'd just front up with measurements of the two parts of the hose length (from body fitting to strut mount, from strut mount to caliper) and samples of the fittings needed at each end, and....wait 30 minutes.

I suspect that is my long ago voice quoted there. Anyway, the point was you either use a banjo bolt end on the line (which seals with a copper washer to the calliper), or a flare nut (which seals on a removable olive inside the caliper).

Ultimately I changed across to aftermarket 8 piston brakes and have done about a bazillion klm on them since. They were a R32 gtr kit that included braided lines, bolted straight on and off I went

You're not wrong, it would be easy enough. I'm just kinda lazy and was hoping for an off-the-shelf setup.

It probably is! That last part is helpful. Thoughts on the other comment about the stock hoses being too short / not enough slack when mounting the larger calipers as the other poster mentioned? I've seen most people say it's just a bolt-on affair, and that's the only post I've seen saying there isn't enough slack in the hose when mounting the 4-pots.

Kinda just leaning towards using the oem lines to be honest, but I may give these a go: https://www.goodridge.co.uk/products/car-brake-kit-for-nissan-skyline-r32-2-6gt-r-1989-1994?variant=12842545348673

I should say that the kit I fitted was for an R32, but had very generous line length (if anything a little too long, have to keep them out of the way). I didn't measure them compared to R32. standard lines, noting the standard lines have a fitting to bolt them to the knuckle.

If you can afford the risk of the car being off the road for a week, I'd try standard lines, as long as they are not taught at full droop on the suspension, I'd just use them...

I'm not sure if this helps or not.

I recently upgraded to R34 Vspec2 Brembo's on the S2 Stag.

I used this braided kit:

https://safebrake.biz/home/292-skyline-gt-r-r34-awd-26tt-brake-upgrade-safebrake-performance-hoses.html

Beyond this I got the R33gtr front brake hard lines, that go over axle hub just behind the dust plate and all lined up beautifully.  The braided lines were same length as the stock ones.

Needed to buy 2x longer bolts for one of the hard mount points for the braided hoses up the front.

Trim rear dust shields so could fit 322mm discs.

It's a pretty straight forward job.

 

ps. the r33gtr hard brake lines have the flare nut so should bolt straight into your callipers.

I ended up buying these: https://www.chasebays.com/products/chase-bays-fenderwell-brake-lines-nissan-r32-r33?variant=41685542764713

 

$69 USD, couldn't beat it. I'm thinking it will be a direct fit but will report back. Ordered some other stuff from that company as well that was back ordered so it's taking a while to get here.

Update: I ended up having to install the Z32 calipers with factory lines as the chase bays R33 ones wouldn't work. The Stagea is missing a bracket for one of the clips on the braided lines. So I had to remove the 'olives' on each caliper which was easy. Drill self tapper in slightly and yank out with hammer. Have to be a little aggressive pulling. But yeah, just reusing OEM lines for now, no issues. It was all bolt on, not even any heatshield trimming.

      @Kinkstaah yeah I initially checked with Chequered as I've used them with a previous car. But they have stopped sourcing and installing Nistune chips. They only do tuning now. I did not want to pull out my ECU and send it away somewhere to have the chip installed. That would mean no driving the Skyline

      Each province differs a bit but we only do mandatory vehicle inspections here for heavy vehicles (Think Ford F350 and up). Those inspections are done by mechanics that are approved by the government. Besides that, it's a free for all as long as the car looks stock.  I asked because I love seeing how engineering differs from country to country. Here in Canada, all designs must be stamped and signed before they can be brought to fruition. (I.E Bridges, structures, Electrical panels, machines, literally everything shy of a wooden table) This can only be done by a professional engineer or professional engineering technologist. Both are protected titles, but the latter having more of a limited scope in what they can stamp. To become a professional engineer, you must complete a 4-5 year bachelors degree in your field of engineering, be part of an engineering order and undergo 4 years of apprenticeship, testing and mandatory continues education. Same story for engineering technologists, but a 3 year associates degree in some form of engineering technology will suffice. If you do not comply, or pretend you're an engineer or technologist, off to jail you go. If you stamp a design that fails, off to jail you go. If you stamp a design that fails and kills someone (I.E Bridge collapse) Off to jail you go for a very long time, your family will be ridiculed on the news, neighbours will surround your home with pitch forks and your dog will disown you.  Same for specialised trades... Example Electricians must undergo 1.5 years of post high school education, 4 years of apprenticeship, testing and hold proper licences. It's for the best, but then we also wonder why we're so short on engineers and tradesmen haha. We also have professional engineers who were only school smart but have no idea how a drill works. They generally go straight into management roles out of school which is also for the best.

      I have a friend who has used Chequered Tuning and CMS. Went to CMS when Chequered had a long wait time which is kind of the norm (for good reason). Was very happy - I'm pretty sure the very simple thing you're asking will be simple.
