Caliso BR901110-01 Vented Drum-In-Hat Disc Brake Rotor

The Caliso BR901110-01 is a vented disc brake rotor with drum-in-hat (DIH) construction, engineered as a direct OE-replacement brake rotor. The vented design features internal cooling vanes that promote airflow between the rotor faces, drawing heat away from the braking surface to reduce brake fade and extend pad and rotor life during normal and demanding driving conditions.

The drum-in-hat configuration integrates a small drum brake surface within the rotor hat, which serves as the parking brake mechanism — a common design on rear axle applications where a separate drum-style parking brake is required alongside disc service brakes.

Key Features:

• Vented construction with internal cooling vanes for improved heat dissipation and reduced brake fade
• Drum-in-hat (DIH) design accommodates integrated drum-style parking brake
• Cast iron construction engineered to OE metallurgical standards for consistent strength and performance
• Non-directional brake surface finish eliminates the need for machining prior to installation and promotes proper pad bed-in
• Precision-balanced and machined to tight tolerances for smooth, vibration-free braking
• Hub-centric design ensures accurate, rattle-free fitment
• Corrosion-resistant coating on hat and edges for extended service life
• Manufactured in an ISO-certified facility to meet OE fit, form, and function requirements

The BR901110-01 is a quality replacement disc brake rotor designed to restore safe, reliable stopping performance. Its OE-matched dimensions and finish make it a straightforward drop-in replacement with no additional machining required.
