A little confused on the brake swap

[ZmeFly]

ive been to several sites regaurding the toyota brake upgrade. read several posts in here as well. what i am confused with is which calipers to use. one says 79-84 toyo 4 wd calipers, 6 cylinder. another says 84-89 toyo 4 runner calipers 6 cylinder.

also there is the thing with the 84 300ZX rotors which i would like to have. now how or where would i get this spacer. could any machine shop make this or??

thanks for any help

As far as the calipers go it's an either/or on the model they come from. Seems to me I remember reading somewhere the 4 Runner caliper may have had a larger piston, but don't know for sure.

I guess the shim could be a flat washer if you had too, not sure how thick it needs to be. I guess that's something you have to find out when you do the swap, since there probably is a little variation in the calipers etc.

Sorry, I don't have all the details but I'll try to give you what I remember. The information is out there and if I run across it again I will let you know. What I remember reading was that there are two different Toyota 4 piston calipers. One will work with a thin rotor, like the stock first generation Z has, and the other (marked with a W??) is for a vented rotor, which you can use on a first gen Z with a 300ZX rotor and either by cutting down the hat of the hub or using a spacer. If it requires a spacer than yes I expect the spacer could be made by any good machine shop and the detailed specifications are on the internet someplace. I don't know if these two calipers correspond the two ranges of Toyota 4x4's you talked about.

I know I have probably raised more questions than I have answered. Hopefully, I can find the info or maybe someone else will bail me out on this one, as is often the case!

Have fun!
