About the Raybestos Specialty - Truck Product Line

The Specialty - Truck line by Raybestos focuses on heavy-duty and truck-specific braking components designed to handle increased load and stress. This disc brake rotor 980186 is part of that line, offering robust construction and vented design to maintain braking efficiency in Mitsubishi trucks and SUVs like the Endeavor and Grandis.

Technical Details and Performance

This Raybestos disc brake rotor features a vented design that enhances heat dissipation, reducing the risk of brake fade during extended use. The rotor’s nominal thickness of 1.025 inches (26.05 mm) ensures structural integrity, while the discard thickness of 0.961 inches (24.4 mm) indicates the minimum safe thickness before replacement is necessary. The 5-bolt mounting pattern with a 4.5 inch (114.3 mm) bolt circle diameter and 0.495 inch (12.55 mm) bolt hole diameter ensures secure installation on compatible Mitsubishi Endeavor and Grandis models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor overheating
• Fixing uneven brake pad wear linked to rotor surface irregularities
• Resolving noise issues such as squealing or grinding from damaged rotors
• Upgrading to a vented rotor for better heat management in heavy-duty use

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 0.961 inches (24.4 mm) before installation. Clean the mounting surface and hub to prevent runout and vibration. Use proper torque specifications for the 5 mounting bolts to secure the rotor firmly. It is recommended to replace brake pads simultaneously to maintain optimal braking performance on Mitsubishi Endeavor and Grandis vehicles.
