Therefore, when the caliper acts, it must slide or float in order to bring the pad on the opposite side in contact with the disc. When the pad flexes, it creates an uneven friction coupling on the rotor’s face. Since 2 pistons are wider than 1, the brake pads are also typically wider which means the brake pad’s surface area is larger, creating more friction and more stopping power. The 2 vs 1 piston advantages won't make up for the loss of clamping force?
