1991 r32 gtr

Here's my quick story. I've google around and searched but I cannot find a similar occurrence which may point out my selection of parts as a whole, caused the problem.

My rear brake lines are very tight and are looking to bust if I move the hubs. Currently, the car is on blocks as suspension is unloaded (dropped). As the suspension loads up wen dropping the car on wheels, the brake line starts to bend the hose at both ends to an unnatural bed radius and started to break the rubber sleeves near the fittings. The suspension arms are all adjust in all the way.

I'll post pics shortly.

My initial thought was that my Rotora brake kit had come with r34 hoses but their length is the same as r32 (26.5cm). Anyone have some insight or ideas? I have not searched for custom lines yet.

Mod list:

Driftworks adjustable suspension arms all around.

Driftworks bushes all around, including diff and main subframe bushes. All polyurethane.

The subframe has been spaced 4mm from the body which I believe is closer than it was with stock bushes.

Whiteline Lower shock bush, poly

Cusco sway bars

Jic magic coilovers with pillow ball uppers

Nissan Larger spline N1/r34 diff output flanges

OS giken rear differential

Rotora 4 piston rear brake kit and SS lines.

All parts are powder coated so maybe 1mm added length to the hub location.

One or all these mods increased my diff to hub ratio but I cannot find anything. And the brake lines appear to be stock length.

Thanks for your help.

Interesting idea. I had though of this but quickly ditched it because there is already a hanger where the hard line connector ends but I guess I could bypass it or bend.

So you're thinking cut the line and add a small section. Hmmm.

Here's some pics...

yeah I'm thinking hoses too as it's the easiest without adding more possible leak spots (joints/couplers). Would just lose my colored hoses I guess. I'm sure nearly any hydraulic hose shop in town would do it or talk to Goodridge USA and give them some lengths.

Just weird that no one else has talked about this issue considering all the parts I used were off the shelf items..

Have you considered that the larger caliper might have moved the connection further from the bodywork?

Are the calipers mounted on the right (correct) sides?

Hmm good train of thought!

Sadly, these calipers were installed 4 years ago (before all other mods) and fit ok as per install manual. Also the hoses came with the calipers for r32 gtr. Lengths are 26.5cm

They would maybe fit better if the banjo was on the bottom but they would be worse when the car was lifted and would be even tighter!!!

    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
    • Probably. I take it that they are also mentioned to be for R34 Skyline? For example.... RDA has that part as RDA7957. I have the dimpled and slotted version of that on my car https://www.ebay.com.au/itm/285518478694?srsltid=AfmBOopKxMuAFpsxZJdB1cam4D5RAj1f9yJyOttPZLAwXVNCOiwlhrIy This is DBA's top one piece equivalent https://www.ebay.com.au/itm/364246686631?srsltid=AfmBOorbb0XHQgqTvZLgQPhg70nqJtGvdojKnugum3O2LFSr2h-obp8D
