Raybestos Element3; Coated Rotor Product Line

The Element3; Coated Rotor line from Raybestos focuses on providing rotors with a protective coating that helps resist rust and corrosion, extending rotor life and maintaining consistent braking performance. This coating is especially beneficial for vehicles like the Ford Crown Victoria, Lincoln Town Car, and Mercury Grand Marquis, which may be exposed to varying weather conditions. The vented design of the 66744FZN rotor improves heat dissipation, reducing the risk of brake fade during extended use.

Technical Specifications and Features

The 66744FZN rotor features a nominal thickness of 1.105 inches (28.050 mm) and a discard thickness of 1.014 inches (25.750 mm), indicating when the rotor should be replaced to maintain safe braking. Its overall height is 2.590 inches (65.800 mm), and the outside diameter is 12.440 inches (316.000 mm), ensuring compatibility with specified vehicle models. The rotor includes five mounting bolt holes with a bolt circle diameter of 4.500 inches (114.300 mm) and a center hole diameter of 2.826 inches (71.800 mm), designed for precise installation on compatible hubs. The vented rotor design aids in heat dissipation, which helps maintain braking efficiency under demanding conditions.

Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Crown Victoria, Lincoln Town Car, and Mercury Grand Marquis
• Addresses brake noise and vibration caused by uneven rotor surfaces
