The 56919FZN rotor incorporates this coating while maintaining strict dimensional standards for optimal braking performance.

Technical Description and Specifications

This disc brake rotor is vented to improve heat dissipation during braking, reducing the risk of brake fade. The drum-in-hat design integrates a parking brake drum within the rotor, compatible with vehicles equipped with rear drum parking brakes. With a nominal thickness of 1.185 inches and a discard thickness of 1.122 inches, this rotor meets OEM specifications for thickness tolerances. The 13-inch outside diameter and 6-bolt mounting pattern ensure proper fitment on compatible Cadillac Escalade, Chevrolet Sierra 1500, Suburban 1500, and GMC Yukon XL 1500 models.

Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor corrosion and surface rust that affect braking efficiency
• Resolving noise issues related to uneven rotor wear
• Improving heat dissipation to prevent brake fade during heavy towing or hauling
• Ensuring compatibility with drum-in-hat parking brake systems on specified vehicles

Installation Notes and Tips

• Verify rotor thickness before installation; replace if below discard thickness of 1.122 inches
• Ensure mounting surfaces and hub are clean and free of debris for proper rotor seating
• Torque mounting bolts to manufacturer specifications to avoid rotor warping
• Inspect brake pads and hardware during rotor replacement for optimal braking system performance
• Compatible with 6-lug wheel configurations on specified Cadillac, Chevrolet, and GMC models
