PowerStop AR85104SCR Disc Brake Rotor - Rear

Rear Coated Brake Rotor Overview

PowerStop AR85104SCR is a rear 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.

This rotor fits 2005-2008 Ford Escape, rear; 2005-2008 Mercury Mariner, rear; and 2005-2006, 2008, 2010 Mazda Tribute, rear. The AR85104SCR part number is also referenced by OE-style interchange numbers for the same application.

Key Features

• Partially coated design with silver epoxy on corrosion-prone areas.
• Coating on the hat, outer edge, and vanes helps resist rust.
• Full cast construction with a smooth, solid rotor surface.
• Mill balanced for consistent operation.
• Matches original equipment weight and vane count for fitment accuracy.

Detailed Description

PowerStop’s coated hat and edge rotor line focuses on OE replacement fit and corrosion resistance. The AR85104SCR uses a full cast, solid rotor design with a 11.89-inch outside diameter, 0.47-inch nominal thickness, and 4.50-inch bolt circle diameter. Its rust-resistant coating is applied to exposed areas that commonly corrode, helping preserve the rotor’s appearance and service life in everyday use. For Ford Escape, Mercury Mariner, and Mazda Tribute rear brake service, this rotor is built to match original equipment specifications closely.

What It Helps Address

• Brake rotor rust on exposed surfaces.
• Uneven appearance behind alloy wheels.
• Replacement needs for worn rear brake rotors.
• Fitment concerns tied to OE-style dimensions and vane count.
• Service issues related to rotor wear and thickness loss.

Installation Notes and Tips

Verify rear fitment by year, make, and model before installation. Confirm rotor dimensions, bolt circle, and solid rotor configuration against the removed part. The AR85104SCR is a direct bolt-on replacement, so it is intended to follow original equipment specifications without custom modification.

Quality Assurance

PowerStop designs this rotor to match original equipment performance and specifications, including weight and vane count, for accurate fitment. The coated surface adds corrosion resistance in areas most exposed to the elements.
