Hello all, looking for some help..

I have a big brake kit that came off of an Auto TT and I’ve gone to fit it on another car and the caliper bolts to the brackets are not in the right location.

they are offset by about 10mm inboard, so was wondering if there was subtle changes to mounting position between turbo/non turbo or a model year change?

From memory, the hubs on my car are from a non-turbo.

Nothing I can find indicates anything different other than potentially the calipers to account for the diameter of the disc. Not the mounting holes.

 

Any help greatly appreciated 

Hi Tom, and welcome to the club!

All I know, is that the diameter of the discs is the same for NA/TT models - however (for earlier models at least) the TT discs were thicker than the NA discs. Hence the calipers were not interchangeable, possibly until much later, when I believe the NA gained the same brakes as the TT.

Hi Richard, thanks for your reply.

You’ve confirmed what I thought, I can find no indication anywhere that the spacing of the caliper relative to the hub was ever changed so I’m really stumped!

Have the hubs been changed for Skyline or 350/370 hubs?

There are some weird and wonderful upgrades out there and what you assume to be stock may not, Ive been caught out by this.

I believe:

1989 - 1991 TT discs were 30mm thick, the NA was 26mm thick. The calipers disc channel width reflected this.

1991 onwards, everything was 30mm thick.

I once bought new discs and pads for an NA converted car and couldnt work out why the discs wouldnt fit. Had to buy new calipers in the end.

Calipers are also confusing. There were the 26mm aluminum , the 30mm cast iron, 30mm aluminium, 30mm aluminium later model, the 30mm akino (or something like that), then I know you can mount skyline R33 calipers with no adapter, but need bigger wheels. R34 calipers fit with a small adaptor, 350 calipers fit out the box, but need bigger wheels and 370 fit with a bracket.

A little guide to stock calipers here.

Thanks for the details.. and you’ve got me thinking now.

I’ve assumed that the z32 that I got the brake setup from had stock z32 hubs.

I guess if the kit came from another Nissan model, they may have swapped the hubs for the kit to work.

Now I’m wondering if R33/R34 front hubs fit a z32?
