Rear coated brake rotor overview

PowerStop AR8587SCR is a rear disc brake rotor built as a direct bolt-on replacement for original equipment. It is engineered for Ford Explorer, Ford Explorer Sport Trac, and Mercury Mountaineer applications with OE-style fitment and corrosion protection on exposed surfaces.

Key features

  • Part number AR8587SCR for easy identification.
  • Partially coated design with silver epoxy on the hat, outer edge, and vanes.
  • Rust-resistant coating helps preserve appearance behind alloy wheels.
  • Full cast, solid rotor construction with a smooth surface finish.
  • Mill balanced to match OE weight and vane count specifications.
  • 5-lug, 114.30 mm bolt circle dimensions.

Detailed product information

PowerStop’s coated hat and edge rotor line focuses on OE-style replacement parts that install directly in place of the original rotor. AR8587SCR uses a full cast, solid design with an 11.85 in. outside diameter, 0.47 in. nominal thickness, and 2.31 in. overall height. The coated areas are placed where corrosion commonly starts, helping the rotor maintain a cleaner look in service. This part cross-references Ford OE numbers 4L2Z 2C026-AA and 5L2Z 2C026-A for the same application.

Compatible with rear brake service on 2002-2010 Ford Explorer, 2007-2010 Ford Explorer Sport Trac, and 2002-2010 Mercury Mountaineer. The AR8587SCR is a practical choice when replacing a worn rear brake rotor on these platforms and when matching OE dimensions matters for proper brake system operation.

Common issues this rotor can address

  • Rotor wear that reduces braking consistency.
  • Surface corrosion on exposed rotor areas.
  • Brake pulsation caused by an out-of-spec rotor.
  • Noise or roughness from a worn rear rotor surface.
  • Fitment problems from using a rotor that does not match OE dimensions.

Installation notes and quality assurance

Install as a rear brake rotor replacement using the vehicle’s original mounting points and verify dimensions before assembly. Confirm the solid rotor design, bolt circle, and overall height match the application before installation. PowerStop designs this rotor to match original equipment performance and specifications, including weight and vane count, for guaranteed fitment.
