Caliso BR901894-01 Vented Disc Brake Rotor with Directional Internal Hat

The Caliso BR901894-01 is a vented disc brake rotor featuring a directional internal hat (DIH) design, engineered to deliver reliable, consistent stopping power as a direct OEM-style replacement. The vented construction channels airflow between the rotor faces to dissipate heat rapidly, reducing brake fade during repeated or heavy braking.

Key Features:

• Vented rotor design for superior thermal management and reduced brake fade
• Directional internal hat (DIH) geometry for precise fitment and hub-centric alignment
• Cast iron construction for strength, durability, and consistent heat dissipation
• Non-directional swirl finish on the braking surface promotes brake pad bedding and eliminates the need for pre-installation machining
• Precision balanced for smooth, vibration-free braking performance
• Corrosion-resistant coating on hat and non-braking surfaces for extended service life
• Engineered to meet OEM specifications for fit, form, and function

The BR901894-01 is a precision-engineered replacement rotor built to restore factory braking performance. Its directional internal hat design ensures accurate hub centering, while the vented core keeps operating temperatures in check under demanding conditions.
