Power Stop's Z26 Street Warrior kit is built for high-horsepower muscle and modified cars, and it comes with everything you need for easy installation, including pads, rotors and stainless-steel hardware. Power Stop pairs its drilled-and-slotted rotors with carbon-fiber ceramic pads, which the manufacturer says combine to provide shorter stops under the most demanding conditions. Buying the matched set in one box avoids mixing pads and rotors from different lines, and it avoids paying separately for hardware. Compared with stock rear brakes, this setup targets repeated hard stops rather than everyday commuting. Search terms this kit fits include Z26 Street Warrior rear brake kit, drilled slotted rotor carbon ceramic pad kit, and 2009-2015 CTS rear brake upgrade.
The application listed for this part is the rear axle of the 2009-2015 Cadillac CTS, so confirm fitment against your VIN before ordering. The manufacturer treats bedding-in as essential: its break-in procedure calls for five moderate-to-aggressive stops from 40 mph down to 10 mph in rapid succession, without letting the brakes fully cool or coming to a complete stop. The purpose of proper break-in is to lay down an even layer of friction material from the pads onto the rotors. Skipping or rushing this step is the most common route to disappointing pedal feel, so plan the bedding run into your install day.
The manufacturer states the kit includes pads, rotors, and stainless-steel hardware, so you have the components needed for the rear axle in one purchase.
The manufacturer describes break-in as critical to optimal performance and asks for five moderate-to-aggressive stops from 40 mph to 10 mph in rapid succession, without letting the brakes cool or coming to a full stop.
Plan on a rear brake job that involves safely lifting the vehicle onto jack stands, removing the wheels, and detaching the caliper without letting it hang from the brake hose. Use a torque wrench for all fasteners and follow the vehicle's service-manual torque values, since the manufacturer's install specifications for this CTS application were not confirmed here. Once the car is back on the ground, complete the manufacturer's break-in sequence before any hard stops or sustained highway driving.
