  Two-piece rotor:

• True floating two-piece rotors with patent pending center-mount design.
• Direct bolt on, easy to install.
• Alloyed iron formula adds strength and heat resistance. Heat treating further improves rotor performance for a more uniform and stabilized microstructure.
• EDP Coating w/cross cut grinding on friction surface.
• Cast iron hat to retain the emergency brake use.

Caliper:

• Piston Material: Upgraded to stainless steel from aluminum that can substantially reduce the heat transfer (approx 1/10 of aluminum) from the pad to brake fluid.
• Double Sealing System: Our uniquely designed double seals in addition to primary hydraulic seal, the dust seal acts as a secondary back up seal (in case primary seal fail) in addition to its normal dust sealing.
• Caliper Body: Re-shaped for tougher stiffness and appealing look.
• Hardware: Brake pad pins and banjo connections were re-designed for easier installation and pad replacement.
• Surface Coating: Liquid paint is used, which is more resistant to chipping than powder coating.
• Light Weight: Weighs only 5 lbs. (compared to old CP4 4.75 lbs.), yet this new RB4000 calipers shall offer extended service life before any rebuilt is required.

Adapter: 7075-T6 Aluminum Alloy
 

Rotor Design:

Our unique and patent pending rotor designs make our discs cooler and last longer.

1. 
   Convergent vane design

   The cooling vanes are of a convergent nozzle design, which increases airflow and turbulence and makes discs cooler.
