PowerStop AR8589SCR Disc Brake Rotor - Front

Overview

PowerStop AR8589SCR is a front disc brake rotor built as a direct bolt-on replacement for original equipment. It is engineered for drivers who want OE-style fitment, corrosion protection, and a clean appearance behind alloy wheels.

Key Features

• Partially coated rotor with silver epoxy on the hat, outer edge, and vanes for corrosion resistance.
• Full cast, vented construction with a smooth surface finish.
• Mill balanced to support consistent brake operation.
• Matches original equipment weight and vane count for proper fitment.
• Compatible with 2002-2005 Ford Explorer front brake applications and 2002-2005 Mercury Mountaineer front brake applications.

Detailed Description

The PowerStop AR8589SCR coated hat and edge rotor is designed to replace the original front rotor on the Ford Explorer and Mercury Mountaineer with OE-style dimensions and performance characteristics. Its vented, full cast design uses a rust-resistant coating on corrosion-prone areas to help preserve the rotor’s appearance and reduce exposed metal on the hat and edge. The smooth braking surface and mill-balanced construction support stable, predictable brake contact. This part cross-references Ford and Motorcraft applications (e.g., 1L2Z 1125-AA, 4L2Z 1125-AA) for the same application.

What It Helps Address

• Corrosion on exposed rotor surfaces and hat areas.
• Brake pulsation caused by worn or out-of-spec rotors.
• Uneven braking feel from a damaged or heavily worn disc.
• Visible rust behind alloy wheels.

Installation Notes and Tips

Verify rotor diameter, bolt circle, and thickness before installation. This rotor uses a 5-lug, 4.50-inch bolt circle and a 12.01-inch outside diameter. Confirm the vehicle’s front brake configuration matches the listed fitment before replacing the rotor.

Quality Assurance

PowerStop designs this rotor to match original equipment specifications, including weight and vane count, for confirmed fitment on listed applications.
