Detailed Product Description

This Raybestos disc brake rotor, part number 582039, is designed to meet the specific braking requirements of Chevrolet Canyon and GMC Colorado trucks. Featuring a vented rotor design, it enhances heat dissipation during braking, reducing the risk of brake fade under heavy use. The coated rotor surface provides protection against rust and corrosion, which is essential for maintaining consistent braking performance over time. The rotor’s smooth surface ensures even pad contact and wear, contributing to quieter operation and longer pad life.

The rotor is a conventional drum-in-hat type, compatible with the original equipment mounting system. It includes six mounting bolt holes with a bolt hole circle diameter of 4.724 inches (120.000 mm) and a bolt hole diameter of 0.630 inches (16.000 mm), ensuring a secure and precise fit. The nominal thickness of 0.709 inches (18.000 mm) and discard thickness of 0.630 inches (16.000 mm) provide clear service limits for maintenance and replacement.
