1.WHY DON’T YOU MAKE A 6 PISTON CALIPER?

Contrary to popular belief, the number of pistons has nothing to do with the performance of the caliper. The most often cited reason for companies that do make 6 piston calipers is that they have more clamping force which, for a given caliper size is patently false. Another reason given is to “equalize” the force on the back of the pad to stop taper, which is also false, (more on that later).
The fact is that clamping force relates to two very important factors, caliper rigidity and piston surface area. The real truth about surface area is that in a given amount of space on one side of an opposed piston caliper, 2 pistons will always have more surface area than 3 smaller ones. One further claim by advocates of 6 piston calipers is that “it enhances the proper location of force on the pad”, which is also immaterial to the results of torque output.
