where to find a small caliper and disc

Anyone have any ideas where I could find a small disc and caliper to use for a back brake? I don't want the gargantous kz type, I'm converting a Suzuki gs rim on the back of my 76, I'm trying to save weight.

It sounds like you have the abilities to.make something fit, perhaps the brakes off a small bike, like a honda rebel. My wife has a 2004 rebel, and if you would like any measurements from its brakes just say the word.

I am using an early R1 rear caliper on my KZ1000 project, it is very small and light. They are cheep on Ebay.


Which Suzuki wheel are you going to use?

Thanks guys , the replies the starting point I was looking for. I 've just been reminded that anything goes when your fabbing ! I like that r1 and cheap are the same part. this may be easier than I thought.
