Detailed Product Description

This PowerStop front disc brake caliper features a cast iron construction that offers strength and resistance to wear under normal driving conditions. The floating caliper design allows the caliper to move laterally, ensuring even pad wear and effective braking. Equipped with a single steel piston measuring 56.90 mm in diameter, this caliper provides consistent hydraulic pressure to the brake pads. The included caliper slides facilitate smooth caliper movement, maintaining proper alignment and brake pad contact. Finished in gray, the caliper maintains a factory-accurate look suitable for restoration or maintenance projects.

The bleeder screw with an M10 x 1.5 thread size allows for proper brake fluid bleeding during installation or maintenance. This caliper does not include mounting hardware or a mounting bracket, so those components must be sourced separately if needed.
