Specialty - Truck Product Line Details

The Raybestos Specialty - Truck product line focuses on heavy-duty and truck-specific braking components. This line is designed to meet the demands of larger vehicles like the Mazda MPV, providing durability and consistent braking performance under load. The 980284 rotor exemplifies this with its vented design and drum-in-hat configuration, which helps dissipate heat and maintain braking efficiency.

Technical Specifications and Features

This disc brake rotor features a vented design that improves heat dissipation during braking, reducing the risk of brake fade. The drum-in-hat type rotor integrates a parking brake drum within the rotor assembly, suitable for vehicles like the Mazda MPV that use this configuration. The rotor’s nominal thickness of 18.05 mm ensures structural integrity, while the discard thickness of 16.0 mm indicates when replacement is necessary to maintain safety. The rotor’s outside diameter of 285.5 mm and overall height of 58.3 mm are engineered for precise fitment and optimal braking surface area.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mazda MPV vehicles
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Restores braking performance affected by rotor thickness below discard limits
• Improves heat management in braking systems with vented rotor design
• Supports parking brake function with integrated drum-in-hat design

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets the nominal thickness of 18.05 mm and is above the discard thickness of 16.0 mm. Properly torque the five mounting bolts to the manufacturer’s specifications using the 114.3 mm bolt circle diameter pattern. Verify the center hole diameter of 72.0 mm matches the hub for a secure fit. It is recommended to inspect brake pads and hardware during rotor replacement for optimal braking system performance.
