Rear coated brake rotor

PowerStop AR8264SCR is a rear disc brake rotor built as a direct bolt-on replacement for original equipment. It is engineered for vehicles that need OE-style fitment, smooth braking performance, and corrosion protection in exposed areas.

Key features

  • Partially coated rotor with silver epoxy on the hat, outer edge, and vanes to resist corrosion.
  • Full cast construction with mill balancing for consistent operation.
  • Solid rotor design with a smooth surface finish.
  • Matches original equipment weight and vane count for fitment consistency.
  • Compatible with 5-lug, 114.30 mm bolt circle applications.

Detailed fitment and design

This PowerStop rear brake rotor is made for direct replacement use on the Buick Park Avenue, Cadillac DeVille, Pontiac Bonneville, and Cadillac Seville. The coated hat and edge help preserve appearance behind alloy wheels while the corrosion-resistant finish protects areas that are prone to rust. AR8264SCR is built to OE specifications for size, mass, and vane count, making it a practical choice for drivers replacing a worn rear rotor with an OE-style part. The smooth, solid design supports stable braking feel in everyday driving.

What it helps address

  • Brake pulsation caused by a worn or uneven rotor surface.
  • Visible rust on the hat, edge, and internal vanes.
  • Reduced braking consistency from rotor wear.
  • Fitment issues when replacing an OE rear rotor with the wrong dimensions.

Installation notes and tips

Verify rotor diameter, thickness, bolt circle, and rear position before installation. This rotor is a direct bolt-on replacement, but the braking system should be inspected for pad wear, caliper condition, and hub surface corrosion during service. Confirm the application against the vehicle’s brake specifications before final assembly.

Quality assurance

PowerStop designs this rotor to match original equipment performance and specifications, including weight and vane count, for confirmed fitment. Part number AR8264SCR is also cross-referenced to 18040482 for the same application.
