Detailed Description

Power Stop AR82189XPR is part of the Power Stop rear drilled, slotted and zinc plated brake rotor line, which focuses on improved cooling, cleaner pad contact, and corrosion protection. The vented rotor design and precision cross-drilled holes help move heat away from the braking surface, while the rounded slots clear away dust, moisture, and gases that can interfere with consistent braking feel. The zinc dichromate coating adds a protective layer against rust, making it a practical choice for daily-driven trucks and SUVs exposed to changing weather.

This rotor set cross-references Centric Parts 120.66079 and Raybestos Brakes 582039 for the same application. If you are replacing rear brake rotors on a Chevrolet Colorado or GMC Canyon, AR82189XPR offers a direct-fit solution that matches OE mounting dimensions and brake system layout.

What It Can Help Address

• Brake fade during repeated stops or heavier braking
• Rotor surface buildup from dust, gas, and moisture
• Rust and corrosion on exposed rotor surfaces
• Uneven braking feel caused by worn or heat-affected rear rotors
• Noise or vibration associated with deteriorated rear brake rotors

Installation Notes and Tips

Verify rear fitment by year, make, and model before installation. This rotor is listed for rear use on 2015-2020 Chevrolet Colorado and 2015-2020 GMC Canyon. Inspect pads, calipers, and related brake components during service, and confirm the hub and mounting surfaces are clean before installing the new rotors. Because this is a direct OE-fit rotor, no special modifications are needed.
