Generally, on 1 and 2 piston sliding calipers, you can frequently see “arches” on the face of a caliper. SPONSORED. Forged billet aluminum bodies, stainless steel pistons, and competition style high-temperature seals put and end to the rust, bore pitting, and seal failures that plague the OE caliper design. The slides and bushings play a critical role on dual-piston calipers. Modern Vehicles typically have open-wheel designs to make it easy to visually confirm how many pistons the calipers have. The pistons on dual-piston calipers may be difficult to retract. 4 and 6 piston calipers are a little more tricky but you can still usually see the outline of the 2 or 3 outboard pistons. The pistons on dual-piston calipers may be difficult to retract. 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.
