Raybestos R-Line Product Line Details

The R-Line by Raybestos focuses on delivering dependable brake components that meet or exceed OEM specifications. This product line emphasizes quality materials and precise manufacturing processes, ensuring that the 582690R disc brake rotor provides consistent performance and durability tailored for vehicles like the Cadillac CT4.

Detailed Product Description

The 582690R disc brake rotor is constructed from cast iron, a material known for its excellent thermal conductivity and wear resistance. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and minimizing the risk of brake fade. With a nominal thickness of 0.909 inches and a discard thickness of 0.787 inches, this rotor maintains structural integrity throughout its service life. The smooth surface finish ensures even brake pad wear and reliable stopping power. Designed with five mounting bolt holes on a 115 mm bolt circle diameter, it fits securely on the Cadillac CT4's hub assembly.

Common Applications and Problem Solving

  • Replacement for worn or warped rotors causing brake pulsation
  • Addressing reduced braking efficiency due to rotor overheating
  • Eliminating noise and vibration from uneven rotor surfaces
  • Upgrading from drum-in-hat rotors to maintain OEM braking feel
  • Ensuring proper fitment and compatibility with Cadillac CT4 brake systems

Installation Notes and Tips

When installing the Raybestos R-Line 582690R rotor, ensure the hub surface is clean and free of rust or debris to promote proper rotor seating. Torque the mounting bolts to the manufacturer’s specifications to avoid rotor warping. It is recommended to replace brake pads simultaneously to optimize braking performance and rotor longevity. Verify the rotor thickness before installation to confirm it meets the minimum discard thickness.
