Hydraulic Disc Rotors


SilverbackHD introduces our series of disc brake rotors for medium and heavy-duty trucks and school buses. Engineered as a complement to the SilverbackHD Quiet Ride™ ceramic-enhanced disc pads, these brake rotors are manufactured with high-density ASTM G3500b grey iron to prevent warpage and effectively dissipate heat. SilverbackHD rotors are manufactured using Intentional Engineering™ to avoid warping and maintain quiet braking. Precision mill balancing creates better brake geometry and less noise.

Benefits of Hydraulic Disc Brake Rotors

  • Less Warping and Less Squealing
    While inferior rotors have been manufactured with grey iron contents as low as 2000 (20,000 psi of tensile strength), the G3500b grey iron provides almost double the tensile strength. This means that the denser iron in our rotors more efficiently dissipates heat away from the wheel end, which avoids warping the rotor or glazing the disc pads and causing squealing.
  • Improved Heat Dissipation for Longer Life
    G3500b grey iron, with high carbon content, has demonstrated better heat dissipation characteristics that provide substantially longer rotor and friction life due to less heat buildup in the wheel end.
  • Corrosion Resistance
    Patented GeoMet coating is applied to every rotor to resist winter’s corrosive agents on our roads, plus provide resistance to solvents like gasoline, brake fluids, transmission fluids, antifreeze and motor oil.
