Can you directly transplant the rotors from a TT to an NA ?

 

Both zeds use aluminium callipers but the TT disc seems to be thicker.

From about 92 onwards (I think), all models used the same brake parts.

Its ok now,

 

I sold my old discs to stewart and his discs were thinner, but turns out he had old discs with new calipers.

 

Explains why his brakes were pish.

 

Just needs a piston pusher for the calipers to get them back in to allow the discs to be put on.

Undo the bleed nipple and they should just slowly push in with a suitable implement (away from the dust seal so's not to tear or pinch it). Keep pressure on the piston then nip up the nipple (ooh err missus), should only need minimal bleeding.

Should be able to push it back by hand with the nipple open. Don't be tempted to force them back with it closed, you risk flipping the seals in the BMC and you don't need that headache.

Yeh,

 

I told Stewart that so hopefully he can do it himself, i'm not the kind of guy to play with another mans nipples. :)

Calipers on NA from 93+ are normally TT ones

 

Rotor size is the same ...

 

NA 28mm Thick

TT 32mm Thick

 

Caliper Slot will all so be bigger to take the TT Disc Aprox 36mm

 

and will fit NA without any problems at all

Sorry to dig up an old thread, if ive read this right, my import NA 1990 300zx will have the 28mm thinner discs? I guess I should measure them just incase one of its previous owners has put TT calipers on it?

They were actually 26mm, they were originally on mine, till i changed to TT calipers and discs. The circumference is the same, its the depth of the disc you need to measure. The TT discs are 30mm

I found the later cast iron calipers to cope better with brake fade too
