Caliso BR901144-01 Vented Disc Brake Rotor - 10-Hole Hat-Shaped

The Caliso BR901144-01 is a vented disc brake rotor engineered for heavy-duty commercial truck and medium-duty fleet applications. Constructed from cast iron to withstand the thermal and mechanical demands of large vehicles, this rotor delivers reliable stopping power and long service life.

Key Features:

• Vented construction with multiple internal vane configurations to force hot air out and draw cool air in, reducing heat buildup and brake fade
• 10-hole, hat-shaped design for proper fitment on commercial truck axle hubs
• 4.45-inch overall height for correct clearance and fitment
• 15-inch outside diameter for maximum braking surface coverage
• Non-directional swirl finish eliminates the need for machining prior to installation and promotes even brake pad bedding
• Precise hub hole chamfer ensures a hub-centric fit for smooth, vibration-free braking
• Coated hat and edge for enhanced rust and corrosion resistance
• 1.32-inch discard thickness with a nominal thickness of 36.5 mm
• 7.25-inch bolt circle diameter with 10 mounting holes at 15.1 mm diameter
• 6-inch center hole diameter for proper hub centering
