Detailed Product Description

This PowerStop rear disc brake caliper is engineered with a cast iron body to withstand the rigors of daily driving and heavy-duty use. The floating caliper design allows for even pad wear and consistent braking force.

The included caliper slides ensure smooth movement and proper alignment during braking. The gray finish provides corrosion resistance to extend the caliper's service life. This caliper does not include mounting hardware or a mounting bracket, so those components must be sourced separately if needed.
