Rear Brake Qs again...

[silviac]

So I got me a BM57 bmc. i think it's off Z32.. so it is the right one? Do I need to do anything before I install this? recond or check for anything?

Also I scored Z32 rear calipers and R33 rear rotors. They can be used together? or should I just go whole R33 hub setup with caliper and disc. Which is easier to install?

Also do i need to recond caliper?

Gonna get R33 handbrake cable Z32 drum and S13 or A31? backing plate..

I think you need to look in the useful threads section - Nicely's Technical Guides, this conversion has been done a number of times before.
As for recon parts, it depends on the condition of the ones you've got and how willing you are to take it all to pieces if they need replacing in the future.
