Caliso BR901786-01 Vented Drum-In-Hat Disc Brake Rotor

The Caliso BR901786-01 is a vented disc brake rotor with drum-in-hat (DIH) design, engineered to deliver reliable stopping performance as a direct OE-style replacement. The drum-in-hat construction integrates a rear parking brake drum into the rotor hat, making it a precise replacement for vehicles that use a combined disc/drum braking arrangement at the rear axle.

Key Features:

• Vented construction promotes airflow between rotor faces for improved heat dissipation and reduced brake fade
• Drum-in-hat (DIH) design accommodates integrated parking/emergency brake systems without requiring separate components
• Non-directional swirl finish eliminates the need for pre-installation machining and promotes faster pad bedding
• Corrosion-resistant coating on the hat and rotor edge for extended service life
• Manufactured to meet OE requirements of fit, form, and function
• Engineered to SAE metallurgical standards for consistent strength, quality, and braking performance
• Precision-balanced design minimizes vibration and brake noise

This rotor undergoes multi-stage quality control testing — including thickness variation, runout, parallelism, and dimensional verification checks — to ensure it meets strict dimensional and weight specifications right out of the box.
