Disc brakes have been around since the 70's. Disc brakes don't make you go faster, look cooler or sound meaner. But, few things are less enjoyable than pulling a trailer with lousy brakes. Not only can it be stressful and needlessly hard work, it can also be dangerous. Good brakes can actually improve your overall abilities by allowing much better control of the trailer at all times.

What is the clamping force?

The clamping force that a caliper exerts, measured in pounds, is the hydraulic pressure (in psi) multiplied by the total piston area of the caliper (in a fixed caliper) or two times the total piston area (in a floating caliper), in square inches. To increase the clamping force it is necessary to either increase the hydraulic pressure or the caliper piston area. Increasing the coefficient of friction will not increase clamping force.
