This caliper is a hydraulic clamp assembly that converts brake fluid pressure into linear force, pressing the pads against the rotor to slow the vehicle, as the live page describes. It carries one or more pistons, high-temperature seals, and a rigid bridge to spread the load across the pad face, so the action stays accurate and the wear stays even. Correct caliper action restores a constant pedal stroke and dependable stopping on both sides of the axle.
Sticking pistons, uneven pad wear, leaking seals, drag that overheats a rotor, and a pull under braking all point to a tired caliper. A fresh unit reinstates even left-to-right clamp force, restores a firm and predictable pedal, reduces the noise that misaligned or sticking slides create, and supports consistent ABS behavior through steady hydraulic response.
