Caliso BR900660-01 Vented Disc Brake Rotor with Directional Inner Hat - Rear

The Caliso BR900660-01 is a rear vented disc brake rotor featuring a directional inner hat (DIH) design, engineered as a direct replacement for select heavy-duty van and truck applications. The vented construction promotes active airflow through the rotor, helping to manage heat buildup during repeated braking and maintain consistent stopping performance.

Key Features:

• Vented rotor design — internal vane structure channels airflow to dissipate heat and reduce brake fade
• Directional inner hat (DIH) — optimized hat geometry for improved airflow and structural rigidity
• Non-directional swirl finish — eliminates the need for resurfacing prior to installation and promotes proper brake pad bedding
• Precision balanced — minimizes vibration and pedal pulsation for smooth, confident braking
• High-quality cast iron construction — delivers durability and thermal stability under demanding conditions
• Rotor may or may not include additional inspection or set screw holes depending on production batch
• Manufactured to meet requirements of fit, form, and function as a direct OE-style replacement
