I just picked up a Kona Caldera and I need some advice on the brakes, the master cylinders specifically. The ones on the bike are pretty rashed up and I'd like to just replace them with newer masters, if possible. I see that the current Hayes Radar has a "flip-flop" design that allows the brakes to be use on either side of the bar. Is there any reason these masters would NOT work with the brake lines currently on the bike? Hayes hasn't changed that aspect of their technology, have they?
