PowerStop Z23 Coated Rear Brake Kit - Cadillac CT5 2020-2025

This Z23 coated brake kit rebuilds the rear axle with Power Stop's carbon-fiber ceramic Z23 pads and fully coated full-cast rotors. The Z23 friction formula is a low dust compound aimed at daily driven cars, and dual-layer rubberized shims damp the noise and vibration that often follow a pad and rotor swap. The rotors are coated inside and out, so the vanes, hat and edges stay clean behind an open wheel design instead of surface rusting. Premium stainless-steel hardware, a pin bushing kit and hi-temp ceramic brake lubricant are in the box, and the kit bolts to the factory calipers with no modification.
