Just a few questions about putting rear brakes on a 180b.

Must fit under 15 inch wheels (MR30 skyline)

What disc do you use, i was thinking evo 6 as that's what we use on the front.
Ive seen a few people use a r32 rear disc, does anyone have a template for this? would like to keep it bolt on.


cheers.

R31 rear disc, calliper and calliper bracket, same as the 510/1600 conversion. These brakes were actually mounted to 610 rear control arms which I then swapped into my 510.
It does indeed bolt on

hi we already have r31 brakes, they are crap the last event we did the caliper jammed and we were using pads in 30km so were looking at other solutions and we have some r32 brakes at home.

I don't mean to be rude, but maybe the excessive pad wear is down to the pads you a using and not the brakes themselves.

the calipers had worked fine for 4 years, they just required high maintenance and we are looking for better rear brakes.
in the case of the pads wearing in 30km it was due to the caliper been jammed on.

sorry but i am NOT interested in using the R31 brakes and would like to use the R32 brakes.

My mate has them fitted on his ipra 1600. He uses a falcon rotor (unsure of dimensions as was already fitted to car), and z32 2 spot rears (same as skyline ones).

To mount the caliper, it uses an r31 caliper mount, then another dog ear mount bolted to that.

Also fits under a 14inch rim I believe.

The R32 callipers have no inbuilt handbrake and as far as I'm aware there's not a disc that will fit that will still give you the option of an internal drum handbrake. Fine for a racecar, not so good for a road car.
There's an early Toyota Corona disc that will fit and gives a nice offset. Stud pattern the same as Datsun, just need to machine out the centre spigot. Only drama being slipping the disc over loses pretty much all of the spigot diameter for the wheels.

R32 2 pot calipers bolt straight to the R31 Vented (internal handbrake) rear arms the R31 rear arms will bolt up to the Datsun cross-member but you will end up with heaps of toe in.
This then opens up more problems with half shaft lengths for diffs etc no rear spring perches (change to coil overs). But what im saying is if your keen to do a complete rear end upgrade then you could go down that path,

Prob not what your after though.

This is why I'm paying heaps for hr31 296mm vented discs/ internal park brake and with mazda 4 spot calipers to be fitted to a skyline (bluebird) irs rear end
I originally wrote 2 spot calipers but there 4 spot

pics and info on these?

not at this time I'm afraid
it may seem like I'm a being a drop kick but I'm not paying for about 2 days of trial and error by a rally car building expert before he could work out how to do it correctly
then pay for the actual conversion just to give it away for free.
I'm picking up the final product next week-end and will talk to the builder about how much this really costs and how much info can be given out.
He may be able to make it a regular swap or because of the time and engineering crap he may never want to do another
The swap is onto a standard skyline IRS
I was going to fit the whole hr31 trailing arms but because of the differences in the arms it upsets the geometry of the rear end

well if you go down the path of making them let me know, Ill buy a pair of adapters.
Im not fussed on a hand brake

These are some photos i took one afternoon when i was board and had nothing else to do so i bolted some parts together,

160J cross member
R200 CLSD HR31
Stock R200 half shafts (a bit to squashed up might work but prob would need shorting)
Z31 5 Stud hubs
HR31 Vented discs (have internal drum handbrake) (re-drilled to suit 5 stud).
R32 Twin pot rear brakes.

I later found some random brake lines at a local store i have no idea what they are from but they fit


Everything bolts straight together only custom work was redrilling brake discs i did this with a battery drill (i don't ever plan on using them will buy new discs).

It just gives you quite a bit of extra toe in but i think that could be adjusted out with a Datsport ARC (i'll let you know one day).
