99 spec rear caliper vs 94??
 

So i purchased a 94 FD where previous owner claims that rear calipers are from 99 (larger)

1. what do i need to look for to verify that these are in fact from 99?
2. what size brake pads am i looking for? is it larger than 94? (i need new brake pads)
3. what size rotors am i looking for? is it larger than 94? (i need new rotors as well)

i apologize for the noob questions.

Bracket that mounts to caliber & disc diameter

do you know what size rotor/ brake pad i would be looking for in this case?

Pads are the same size. Rotors are in this thread

314x20

There is no such thing as '99 brakes.

There are two types of brakes fitted as standard to FD's, the larger of the two (314x32 front and 314x20 rear) were fitted from '92 onwards to certain models e.g. the RZ, RS, RS-R, SP, SR etc. The very early pre '92 RZ's had the smaller brakes.

'99 FD's have the same brakes as USDM FD's unless they're a special edition e.g. an RS, RZ or SR model.

Thanks for the info everyone!
I called stop tech and apparently, they do not have anything in the size of 314.
i have measured my rotors and they are in fact 314.

now the question is, does anybody know where i can purchase these rear rotors thats 314 in size? https://cimg7.ibsrv.net/gimg/www.rx7...60d3c90e34.jpg
