Caliso BR900938-01 Vented Disc Brake Rotor with Directional Internal Hat

The Caliso BR900938-01 is a vented disc brake rotor with a directional internal hat (DIH) design, engineered as a precision replacement for OEM disc brake systems. Vented rotors feature internal cooling vanes between the two rotor faces, promoting airflow that dissipates heat generated during braking — helping to reduce brake fade and extend pad and rotor life under normal and demanding driving conditions.

Key Features:

• Vented Construction: Internal vane design channels airflow through the rotor to manage heat buildup and maintain consistent braking performance
• Directional Internal Hat (DIH): The directional internal hat geometry optimizes rotor rigidity and thermal management for improved durability
• OEM Replacement Fit: Engineered to match original equipment specifications for proper fitment and function
• Cast Iron Construction: High-quality cast iron provides the strength and thermal capacity expected of a performance-grade brake rotor
• Non-Directional Rotor Surface: Ready for installation without additional machining

The Caliso BR900938-01 vented brake rotor is a direct-replacement component designed to restore safe, reliable stopping power. Always replace brake rotors in axle pairs and inspect brake pads, calipers, and hardware at time of installation.
