• Overall height of 3.504 inches (89 mm) and outside diameter of 15 inches (381 mm)
• Six mounting bolt holes with a bolt circle diameter of 6.75 inches (171.45 mm)
• Center hole diameter of 5.395 inches (137.05 mm) for precise fitment
• Conventional solid or drum-in-hat type rotor design

Detailed Product Specifications

This Raybestos disc brake rotor features a vented design that enhances airflow to reduce heat buildup during braking, which is critical for truck models that endure heavy loads and frequent stops. The smooth surface finish ensures even pad contact and consistent braking performance. With a nominal thickness of 1.437 inches and a discard thickness of 1.320 inches, this rotor meets strict wear standards to maintain safety and performance. The rotor’s 15-inch outside diameter and 3.504-inch overall height accommodate a range of medium to heavy-duty truck brake systems. The six mounting bolt holes, each 0.573 inches in diameter, are arranged on a 6.75-inch bolt circle diameter, ensuring compatibility with specific truck makes and models requiring this configuration.

Specialty - Truck; Coated Rotor Product Line

The Raybestos Specialty - Truck; Coated Rotor line is designed specifically for truck applications where durability and corrosion resistance are essential. The coating applied to this rotor helps protect against rust and environmental damage, extending the rotor’s service life in harsh operating conditions. This product line focuses on providing rotors that maintain structural integrity and braking efficiency for commercial and heavy-duty trucks.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Upgrading corroded rotors to improve braking reliability
• Addressing overheating issues in heavy-duty truck braking systems
• Ensuring proper fitment for trucks requiring a 6-bolt vented rotor
• Maintaining braking performance in trucks exposed to harsh environments

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 1.320 inches before installation. Clean the mounting surface and verify the six mounting bolt holes align with the vehicle’s hub. Use proper torque specifications for mounting bolts to avoid rotor warping. This rotor is designed for conventional drum-in-hat type brake systems, so confirm compatibility with your truck’s brake assembly. Avoid contaminating the rotor surface with grease or oil during installation to maintain optimal braking performance.
