Caliso BR900774-01 Vented Disc Brake Rotor with Directional Internal Hat

The Caliso BR900774-01 is a vented disc brake rotor with a directional internal hat, engineered as a direct-fit replacement for disc brake systems requiring this specification. The vented two-piece construction features internal cooling vanes between the two rotor faces, promoting continuous airflow through the rotor to dissipate heat generated during braking and reduce the risk of brake fade.

The directional internal hat design optimizes the angle of the cooling vanes for maximum thermal efficiency on a specific side of the vehicle, ensuring proper heat management and consistent braking performance under normal and demanding driving conditions.

Key Features:

• Vented rotor design — internal cooling vanes channel air through the rotor to reduce heat buildup and brake fade
• Directional internal hat — side-specific vane geometry maximizes cooling efficiency
• Cast iron construction for durability and reliable friction surface performance
• Precision-machined friction surfaces for consistent pad contact and smooth brake feel
• Direct-fit replacement design for straightforward installation

The Caliso BR900774-01 vented brake rotor is a reliable OE-replacement solution, restoring safe, confident stopping performance when your original rotor has reached its wear limit or been damaged.
