Clip said:why do designers not put two calipers on a disc? they make multi-piston calipers, why not make multi-caliper brakes. one on the front and back of each disc. i know itd be pretty damn hard to get them to push at the same time with the same pressure, is that the only reason?
prolly space and cost, its cheaper to have one housing with multiple pistons then more making 2 housings.
making equal pressure is the basis of using a hydrolic system. making them put equal pressure at the same time is the easiest part of it.
