PowerStop AR8588SCR Disc Brake Rotor - Front

Coated front brake rotor

The PowerStop AR8588SCR is a direct bolt-on front disc brake rotor built to match original equipment dimensions and performance targets. It is a fitment-based replacement for select Ford Escape, Mercury Mariner, and Mazda Tribute applications, with a corrosion-resistant finish that helps preserve appearance behind alloy wheels.

Key features

• Part number AR8588SCR for easy identification.
• Partially coated design with silver epoxy on corrosion-prone areas.
• Full cast, vented rotor construction with a smooth friction surface.
• Mill balanced for consistent operation.
• Matches OE weight and vane count for proper fitment.

Detailed description

PowerStop’s coated hat and edge rotor line focuses on OE-style replacement with practical corrosion protection. On the AR8588SCR, the hat, outer edge, and vanes receive a protective coating to help resist rust where exposed metal is most vulnerable. The vented, full cast design supports stable braking performance, while the smooth surface and OE-matched specifications make it a straightforward choice for front brake service on the Ford Escape, Mercury Mariner, and Mazda Tribute. This part cross-references Ford and Mazda OE numbers for the same application.

What it is used for

• Replacing a worn or rusted front brake rotor.
• Restoring proper braking surface thickness and finish.
• Addressing rotor vibration caused by wear or corrosion.
• Maintaining a cleaner appearance behind alloy wheels.

Installation notes and tips

Verify rotor diameter, bolt pattern, and thickness before installation. Confirm the vehicle uses a front vented rotor with a 4.50-inch bolt circle and five lug holes. Inspect pads, caliper hardware, and hub condition during brake service to help ensure even contact and proper rotor seating.

Quality assurance

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