Detailed Description

Part number AR85135XPR is engineered for rear brake service where stable pedal feel and heat control matter. The vented rotor design supports cooling under repeated stops, while the drilled and slotted face helps maintain a cleaner friction surface. The zinc-plated finish adds a protective layer against rust, making this rotor a practical choice for daily driving and demanding conditions. This part cross-references Raybestos Brakes 680898 for the same application.

Compatible With 2010-2011 Ford Ranger, rear; 2010 Mazda B2300, rear; and 2010 Mazda B4000, rear. If you are searching for a rear drilled and slotted brake rotor for Ford Ranger 2010-2011 or a rear brake rotor for Mazda B2300 and Mazda B4000 2010, AR85135XPR matches the listed OE-style applications.

What It Helps Address

• Brake fade during repeated stops
• Rotor surface buildup from dust and moisture
• Rust formation on exposed rotor surfaces
• Uneven braking feel from worn rear rotors
• Noise and vibration associated with degraded rotor surfaces

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and rear axle application before installation. Clean the hub mounting surface thoroughly to help prevent runout-related brake pulsation. Follow the vehicle manufacturer’s torque specifications during wheel installation and inspect pads, calipers, and hardware condition at the same time. AR85135XPR is a direct-fit replacement and does not require special modifications when used on the listed vehicles.

Quality Assurance

Power Stop manufactures this rotor with precision machining and a corrosion-resistant zinc finish to support consistent fit and finish. The AR85135XPR part number is also used in OE-style cross-reference listings for the same rear brake applications.
