Detailed Product Description
This Raybestos disc brake rotor, part number 582455, is part of the Specialty - Truck; Coated Rotor product line, which focuses on heavy-duty applications requiring robust braking components. The vented rotor design improves airflow to dissipate heat generated during braking, reducing the risk of warping and brake fade. The coated finish helps protect the rotor from rust and corrosion, which is especially beneficial for vehicles exposed to harsh weather or road salt.
With a nominal thickness of 1.102 inches and a discard thickness of 0.984 inches, this rotor maintains structural integrity throughout its service life. The 12.638-inch outside diameter and 1.791-inch overall height ensure proper fitment and compatibility with the specified vehicle models. The five mounting bolt holes and 4.724-inch bolt circle diameter align precisely with the brake assembly of Buick Envision, Cadillac ESCALADE IQ, Hummer EV Pickup, Hummer EV SUV, Chevrolet Silverado EV, and GMC XT4 models.
Applications and Problem Solving
- Replacement for worn or warped rotors causing brake pulsation or noise
- Upgrading corroded rotors to coated versions for improved longevity
- Addressing brake fade issues in heavy-duty or frequent stop driving conditions
- Ensuring proper rotor thickness to maintain braking performance and safety
- Compatibility with electric and traditional truck and SUV models requiring vented rotors
Installation Notes and Tips
- Verify rotor thickness before installation; replace if below discard thickness of 0.984 inches
- Ensure mounting surfaces and bolt holes are clean and free of debris for proper fitment
- Use recommended torque specifications for the five mounting bolts to avoid rotor distortion
- Inspect brake pads and calipers during rotor replacement for optimal braking system performance
- Allow for proper bedding-in of new rotors and pads to achieve consistent braking
