Detailed Product Description

The Raybestos R-Line 580029R rotor is a vented disc brake rotor featuring a drum-in-hat design, which integrates a parking brake drum within the rotor assembly. This design is commonly used on SUVs and trucks, providing both braking and parking brake functions in one component. The rotor measures 12.8 inches in outside diameter and has an overall height of 3.345 inches, ensuring compatibility with specific vehicle brake systems. Its nominal thickness of 0.785 inches allows for effective heat management during braking, while the discard thickness of 0.728 inches indicates the minimum safe thickness before replacement is necessary.

With six mounting bolt holes and a 5-inch bolt circle diameter, this rotor fits securely on compatible hubs. The center hole diameter of 3.094 inches ensures proper alignment on the vehicle’s wheel hub. The vented design improves cooling by allowing air to flow between the rotor surfaces, reducing the risk of brake fade under heavy use.
