Detailed Product Specifications

This disc brake rotor features a nominal thickness of 23.2 mm and a discard thickness of 21.0 mm, ensuring it meets OEM standards for wear limits. The rotor's outside diameter measures 334.3 mm, with an inside diameter of 247.0 mm, and an overall height of 82.6 mm. The vented construction enhances heat dissipation during braking, reducing the risk of warping under heavy use. The rotor includes six mounting bolt holes arranged on a 120.0 mm bolt circle diameter, and six stud/lug holes with a diameter of 15.95 mm, ensuring precise fitment on Chevrolet Canyon and GMC Colorado vehicles. The drum-in-hat design integrates a parking brake drum, eliminating the need for a separate component.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Upgrading rusted or corroded rotors to restore braking efficiency
• Addressing brake noise due to uneven rotor surfaces
• Ensuring proper fitment for Chevrolet Canyon and GMC Colorado disc brake systems
• Maintaining braking performance in vehicles with integrated parking brake drums

Installation Notes and Tips

When installing the Raybestos R-Line 582743R rotor, ensure the mounting surfaces are clean and free of debris to prevent uneven rotor seating. Verify rotor thickness before installation to confirm it meets minimum discard specifications. This rotor is non-directional, allowing installation on either side of the vehicle. Use proper torque specifications for mounting bolts to avoid rotor distortion. Since bearings and ABS tone rings are not included, reuse existing components or source separately as needed.
