z20/jza70 brake interchangability

[forey]

had a search and didint come up with anything,

do a70 discs fit up without mods?

the guy at abs said that the jza70 and z20 pads look virtually exactly the same

can anyone confirm asap?

cheers

yes the rears are. i wrote something about this in the Z20 thread, lemme go dig it up

fronts are different between gz though and mz/jz

[forey]

what about the pads? if not where could i possibly get some?

[ReQuieM]

There a two different sized front brakes available on the a70/z20 chassis, on the supras all the JZA70s and MA70 had the larger ones, while some of the earlier GA70's had the smaller ones. IIRC soarers have the same smaller front brakes as the GA70's, a soarer guy might be able to confirm for me.

All the rears are the same, but the front disc are difference sizes on the small and larger ones. IIRC the calipers are also the same but the 'housing' or whatever you call it that the caliper bolts onto, which then bolts onto the hub is different to allow for the bigger/smaller disc. I'm not sure if this impacts on the pads, tho I'm pretty sure they are the same... best bet is to take one of you used pads into the shop and have them lay it over the full sized pic they will have in the order book.

IMHO Your best option is to get your hands on some larger a70 calipers and housing (which bolt up) and get the supra dics. As its easier to get replacement consumables for the supra brakes.

thats correct. i have all the part numbers i posted somewhere in the Z20 thread but the shitty search function in vBulletin is not letting me find the exact post..

[forey]

for the time being i just baught some jza70 pads, apparently .3mm thicker than the z20 ones but the disc will be warn so it shouldnt be a problem.

EDIT - Bingo! Found It!

Toyota will obviously stock all parts..

[doobs]

The rears on all A70/Z20s are the same...

However the fronts are different... The GA70/Z20s have smaller disks (270mm) than the JZA-MA70s (300mm), therefore the bracket that holds the caliper to the hub is different.

To use JZA-MA70 disks on a z20 you will need the bracket from the JZA-MA70... The piston/caliper is the same, so you can swap the bracket without disconnecting the lines if you dont want to bleed the system...

sounds good, thanks guys

assuming the mz21 is same as mz20 as they share the best engine in the world, teh 7m?

[hamgatan]

*hovers over the neg rep button*

[Kedderz]

sarcasm is the fail in text form

but seriously, they would be the same id assume?

[hamgatan]

yes they are the same. dont think the hubs are though... didn't Z21 have ABS?

[Kedderz]

as did the mz20 I owned. Still good to know as ill be needing new discs ;-)

[Kedderz]

Im just sourcing come front ma70 slotted rotors, $199 for two fronts, can I just confirm I need the brackets from the ma70 that holds the caliper to the hub?
