Caliso BR54119-01 Vented Disc Brake Rotor with Directional Inner Hat - Rear

The Caliso BR54119-01 is a rear vented disc brake rotor designed for heavy-duty automotive applications. Featuring a directional inner hat (DIH) design, this rotor promotes optimized airflow and more efficient heat dissipation during demanding braking cycles, helping to maintain consistent stopping performance under load.

Constructed from high-grade cast iron, this rotor is engineered to meet the fit, form, and function requirements of the original equipment specification. The vented design uses internal cooling fins between the two rotor faces to draw heat away from the braking surface, reducing brake fade and extending pad and rotor service life.

Key Features:

• Vented construction with internal cooling fins for superior heat management
• Directional inner hat (DIH) geometry for optimized thermal performance
• 10-bolt mounting pattern for heavy-duty fitment
• Outside diameter: 394.8 mm (15.54 in)
• Discard thickness: 36.0 mm
• Nominal thickness: 37.9 mm
• Cast iron construction for durability and reliable stopping power
• Engineered to OEM fit, form, and function specifications
