Key Features

• Partially coated rotor with silver epoxy on the hat, outer edge, and vanes.
• Rust-resistant coating helps preserve appearance behind alloy wheels.
• Full cast, vented design with a smooth friction surface.
• Mill balanced for consistent operation.
• Built to match original equipment weight and vane count.
• AR82193SCR part number for easy identification.

Detailed Description

PowerStop AR82193SCR is a coated rear brake rotor designed for direct replacement use on select Cadillac, Chevrolet, Buick, and GMC applications. The vented, full cast construction measures 12.41 inches in outside diameter with a 120 mm bolt circle and six lug holes, and it uses a smooth surface with nominal thickness of 0.91 inches. The silver epoxy coating covers corrosion-prone areas to help maintain a cleaner appearance behind the wheel while supporting OE-style performance and fit. This rotor is a practical choice for Cadillac XT5, Chevrolet Traverse, and GMC Acadia rear brake service where original-equipment dimensions matter.

PowerStop’s coated rotor line focuses on replacement parts that mirror factory specifications while adding corrosion protection to exposed surfaces. AR82193SCR follows that approach with a direct bolt-on design and OE-matched weight and vane count for straightforward service work.

Common Repair Uses

• Replacing a worn rear brake rotor with correct OE-style dimensions.
• Addressing brake pulsation caused by rotor wear or thickness loss.
• Restoring braking performance after heat checking or surface scoring.
• Reducing visible rust on exposed rotor surfaces behind alloy wheels.
• Servicing rear brake systems on compatible Cadillac, Chevrolet, Buick, and GMC models.

Installation Notes and Tips

Verify rotor diameter, bolt circle, and thickness before installation. This rotor is a rear application and should be matched to the vehicle’s original brake specifications. Clean the hub mounting surface before installing the new rotor to help prevent runout issues. Confirm fitment for the specific Cadillac XT5, Chevrolet Blazer, Buick Enclave, Cadillac XT6, Chevrolet Traverse, or GMC Acadia application before ordering.

Quality Assurance

PowerStop designs this rotor to match original equipment performance and specifications, including weight and vane count, for guaranteed fitment. The coated surfaces add corrosion resistance where exposed metal is most vulnerable.
