GMC Sierra Brake Calipers convert hydraulic pressure into the clamping force that squeezes the pads on the rotors, allowing the truck to stop or slow down effectively. Sierra Brake Calipers have either steel or phenolic pistons in cast iron bodies with a seal and dust boot to hold fluid and prevent contamination. Bleeder screws allow the release of any trapped air. Throughout the years, GMC Sierra pickups have utilized two primary styles of Brake Calipers, fixed and floating. Fixed units are rigidly bolted in place and multiple opposed pistons press both pads evenly, providing a stronger bite and balanced wear. Floating types are mounted on sliding pins. They have one or more pistons on the inboard side. The piston pushes the pad. Then the whole caliper glides inwards to clamp the outer pad. This design makes for a simpler lighter package. It can stick if the pins corrode. Some designs of floating rear calipers feature a screw type parking brake built into the piston. Drivers should look for leaks, uneven pad wear, pulls, or dragging that mean a bad Brake Calipers requires attention to keep their GMC stopping safely and ensure reliable Brake Calipers performance.
