How universal are the rear brake calipers on the 95+ kdxs? Will calipers from other bikes/models fit? I am in the need for a new one. I actually only need the part of the caliper that has the push cyclinder on it. can i get one of these that will match up to the mounting piece? where should i look to get a new caliper, used would probably be ok. i will email FRP, ****, etc. or if they are universalish, should i look at a trick aftermarket one?
