Detailed Product Description

This Power Stop rear brake rotor pair features a vented rotor design that improves heat dissipation during braking, reducing the risk of brake fade under heavy use. The drilled and slotted surface enhances water and debris evacuation from the rotor face, maintaining consistent braking performance in various driving conditions. The zinc plating provides a protective layer against rust and corrosion, which is especially beneficial for vehicles exposed to moisture and road salt.

The rotors have a nominal thickness between 19.00 mm and 22.00 mm, with a discard thickness of 19.00 mm, helping technicians determine when replacement is necessary. The overall height measurements of 2.00 inches and 51.50 mm, along with an outside diameter of 13.50 inches (342.00 mm), ensure proper fitment and compatibility with the rear brake assemblies of Ford Expedition and Lincoln Navigator models. The mounting bolt hole circle diameter of 135.00 mm (5.30 inches) and six lug holes provide secure installation.
