Rust Prevention Technology (RPT™)

Raybestos® RPT Rust Prevention Technology™

Judge this Rotor by its Cover

Open-wheel designs on modern vehicles leave brake parts, particularly rotors, more exposed to the elements. If a rotor is uncoated, corrosion and red rust begin to form immediately.

Raybestos® RPT Rust Prevention Technology™ coated rotors use a propriety finishing technology to coat each rotor’s entire surface, including the cooling vanes. The full Grey Fusion 4.0™ coating helps resist corrosion and significantly delays rust-induced performance issues.

The Raybestos coated rotor is ideal for drivers in rust-prone areas, including:

  • The rust belt, where aggressive snow and ice melt chemicals accelerate the corrosion of rotors
  • Coastal regions with salt in the air and high humidity

Our coated rotors are built to endure the harshest of weather conditions and deliver:

  • Best-in-class performance
  • Ultra-smooth braking
  • Maximized friction life

Design and Material

Our RPT Rust Prevention Technology™ rotors are developed from OE samples and made with G3000-qualified material, guaranteeing form, fit and function for a dependable performance.

Coating

Our coated rotors are coated on their entire surface with a proprietary full Grey Fusion 4.0™ coating. The rotors are put through 300 plus hours of salt spray testing, which:

  • Exceeds the OE requirement for car and truck rotors
  • Certifies the coating prevents rust and corrosion

Cooling Vanes

By coating the cooling vanes on RPT Rust Prevention Technology™ rotors, it keeps the vanes clear of rust and corrosion for optimal airflow and cooling.

SAE Standard for Tensile Strength

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

Finish

A non-directional ground finish provides a product that is ready to install right out of the box

Lateral Runout & Thickness Variation

Our coated rotors come with a lateral runout of 0.004″ or less and a thickness variation of less than 0.0005”, ensuring:

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

Mill Balanced Edges

Our coated rotors are mill balanced and 100 percent validated. This helps minimize the thickness variation on the rotor and leads to:

  • Proper balance
  • Minimized vibration
  • Quieter and smoother stopping
