Detailed Specifications and Design Features

This Raybestos disc brake rotor features a vented design that enhances heat dissipation during braking, reducing the risk of brake fade in heavy truck applications. The nominal thickness of 1.535 inches (39.000 mm) ensures a robust braking surface, while the discard thickness of 1.420 inches (36.050 mm) provides a clear wear limit for safe operation. The rotor’s overall height of 3.400 inches (86.350 mm) and outside diameter of 15.370 inches (390.400 mm) are engineered to match specific truck brake systems requiring 10 mounting bolt holes arranged on a 7.250-inch (184.150 mm) bolt circle diameter. The center hole diameter of 6.003 inches (152.500 mm) allows for precise hub fitment, ensuring proper alignment and balance.

Specialty - Truck Product Line Details

The Raybestos Specialty - Truck product line focuses on components designed specifically for heavy-duty truck braking systems. This line addresses the unique demands of commercial and industrial vehicles by providing parts that meet stringent durability and performance standards. The 56995 disc brake rotor is part of this line, offering compatibility with truck models that require vented, conventional rotors with specific mounting configurations.

Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Upgrading to vented rotors to improve heat management in heavy trucks
• Restoring braking efficiency on trucks experiencing reduced stopping power
• Addressing rotor thickness below discard limits to maintain safety
• Ensuring proper fitment for trucks requiring 10-bolt mounting rotors

Installation Notes and Tips

Ensure the rotor surface is clean and free of rust or debris before installation. Verify the mounting bolt hole pattern and center hole diameter match the vehicle hub specifications. Use a calibrated micrometer to measure rotor thickness and confirm it meets or exceeds the nominal thickness. Proper torque specifications should be followed when securing the rotor to avoid warping. It is recommended to inspect brake pads and other related components during rotor replacement for optimal braking performance.
