Specialty Truck, School Bus & Medium Duty Rotors

Raybestos® Specialty Rotors are the ultimate solution for noise-prone applications, including truck, medium duty and school bus applications. 

Vehicle-specific cooling vane configurations and application-specific iron combine to:

  • Dampen noise
  • Improve brake responsiveness

This ensures super smooth and ultra-quiet braking over a longer period of time.


Design & Material

Our vehicle-specific design matches OE form, fit and function, providing ultimate strength and performance.

Made from an enhanced iron material, our Specialty Rotors include the following features:

  • Maximized noise suppression
  • Long, thick carbon fibers to absorb noise
  • Higher thermal conductivity to keep brakes running cool, quiet and vibration free

Cooling Vanes

We take the time to match the cooling vanes on our Specialty rotors to OE specifications, ensuring:

  • Optimal cooling
  • Reduced fade
  • Less noise
  • Increased pad life


Depending on the application, our Specialty rotors come either fully coated with a Grey Fusion 4.0™ or a black fusion coated hat for rust protection. 

SAE Standard for Tensile Strength

Our rotors meet the SAE standard for tensile strength, providing structural integrity and maximum service life.

Turned Finish

A turned finish minimizes noise and improves responsiveness for smoother stops.

Lateral Runout & Thickness Variation

Our Specialty rotors come with a lateral runout of 0.002″ or less and a minimal thickness variation of less than 0.0004”, ensuring:

  • Less pedal pulsation
  • Less brake noise
  • An extended pad life

Mill Balanced

Specialty rotors are mill balanced and 100 percent validated. This helps minimize the thickness variation on the rotor, guaranteeing:

  • Proper balance
  • Minimized vibration
  • Quieter and smoother stopping
