PowerStop AR85124XPR Disc Brake Rotor Set - Rear

Rear Brake Rotor Upgrade for Expedition and Navigator

PowerStop AR85124XPR is a rear drilled and slotted brake rotor set built for direct OE-style replacement on select Ford Expedition and Lincoln Navigator applications. The vented rotor design, cross-drilled surface, and rounded slots are intended to improve heat management and keep the friction surface cleaner during repeated braking.

Silver zinc dichromate plating adds rust and corrosion resistance, while the direct fit design helps simplify replacement on compatible rear brake systems. This part cross-references Raybestos Brakes 680507 for the same application.

Product Details

Power Stop’s rear drilled, slotted and zinc plated rotor line focuses on brake cooling, surface cleaning, and corrosion resistance in a direct replacement format. AR85124XPR uses precision cross-drilling and rounded slots to help move gases, dust, and moisture away from the pad contact area, supporting consistent rear brake performance on 2007-2017 Ford Expedition and 2007-2017 Lincoln Navigator vehicles. The vented rotor design and OE-style dimensions make it a practical choice for rear brake service where fitment and rotor finish matter.

Common Brake Issues Addressed

• Brake fade during repeated stops
• Rotor surface rust and corrosion buildup
• Dust and moisture accumulation on the braking surface
• Uneven pad contact caused by glazed or contaminated rotors
• Reduced braking consistency from heat buildup

Installation Notes

Compatible With 2007-2017 Ford Expedition, rear. Compatible With 2007-2017 Lincoln Navigator, rear. Verify rotor dimensions, bolt pattern, and rear brake configuration before installation. Clean the rotor surface before use and follow the vehicle manufacturer’s brake service procedures for pad bedding and torque specifications.
