    Calipers from just about any other 1980+ GS with two rotors. Look at the shape of the brake pad.

    The caliper brackets are different between models, but the calipers themselves are the same.


    If what you're really asking about is an upgrade, there are adapter brackets that will allow you to mount up a modern multipiston caliper. I don't know of anyone making them right now, but there have been a few over the years. Perhaps you can post up in Parts Wanted and scare up a set.

    Also, before you get all excited about an upgrade, make sure your stock brakes are working correctly. GS brakes work astonishingly well with good modern brake pads and stainless braided brake lines. You'll may also need to rebuild the calipers and master cylinder to restore proper function.

      Brian's right, though being an American of course he never learned the alphabet down as far as X so he didn't include the GSX range. 2 types of pad (FA51s and FA65s) on those models - as long as you get calipers from a GS or GSX with those pads they'll fit. The calipers are slightly different and the pads don't cross over. The calipers fitted with the 51s are I think marginally better.
