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.
