Detailed Product Description

The Raybestos R-Line 56140R disc brake rotor is a vented rotor designed to provide effective heat dissipation during braking, reducing the risk of brake fade. Its nominal thickness of 0.800 inches (20.300 mm) ensures structural integrity, while the discard thickness of 0.736 inches (18.700 mm) indicates the minimum safe thickness before replacement is necessary. The rotor features a 10.200-inch (259.100 mm) outside diameter and an overall height of 1.885 inches (47.900 mm), making it suitable for specific mid-size and compact vehicles.

This rotor includes five mounting bolt holes arranged on a 100 mm (3.937 inch) bolt circle diameter, compatible with vehicles such as the Buick Skylark, Oldsmobile Achieva, and Pontiac Sunfire. The center hole diameter of 2.300 inches (58.400 mm) ensures proper fitment on the hub assembly. As a conventional rotor, it is designed for use with drum-in-hat brake systems.
