Rear brake rotor replacement
PowerStop AR8671SCR is a rear disc brake rotor built as a direct bolt-on replacement for original equipment. It is designed for vehicles that need a solid rotor with corrosion protection on exposed surfaces and a clean finish behind alloy wheels.
Key features
- Partially coated rotor with silver epoxy on the hat, outer edge, and vanes
- 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
- Rust-resistant coating helps preserve appearance in exposed areas
Detailed fitment and design
This PowerStop rear rotor is engineered for direct replacement use on Chevrolet Uplander, Pontiac Montana, Buick Terraza, and Saturn Relay applications. The AR8671SCR uses a 300 mm outside diameter, 12.00 mm nominal thickness, and 10.50 mm discard thickness, with a 115.00 mm bolt circle and six lug holes. Its coated hat and edge help reduce corrosion where the rotor is most exposed, while the solid, smooth design supports OE-style braking performance.
PowerStop’s coated hat and edge rotor line focuses on practical corrosion resistance and OE-style dimensions. For shoppers looking for a rear brake rotor for Chevrolet Uplander, Pontiac Montana, or Buick Terraza service, this product line emphasizes direct bolt-on replacement and specification matching rather than modified fitment.
What this rotor helps address
- Corrosion on the hat, edge, and vane areas
- Brake pulsation caused by worn or out-of-spec rotors
- Uneven braking feel from a damaged rear rotor
- Visible rust behind alloy wheels
- Replacement needs for rear brake service on listed applications
