Detailed Product Specifications

The Raybestos R-Line 8529R rotor features a vented design that enhances heat dissipation during braking, reducing the risk of brake fade under demanding conditions. With an outside diameter of 15 inches (381 mm) and an overall height of 6.8 inches (172.7 mm), this rotor is engineered to meet the specifications required by certain full-size trucks and SUVs. The nominal thickness of 1.435 inches (36.450 mm) ensures structural integrity, while the discard thickness of 1.320 inches (33.550 mm) indicates the minimum safe thickness for continued use.

The rotor includes 10 mounting bolt holes with a diameter of 0.807 inches (20.500 mm) arranged on an 11.250-inch (285.750 mm) bolt circle diameter, providing secure attachment to the hub. The center hole diameter of 9.375 inches (238.150 mm) allows for proper centering on the vehicle’s hub assembly. This conventional rotor type is designed for vehicles utilizing drum-in-hat brake configurations.
