Caliso BR53019-01 Front Vented Disc Brake Rotor

The Caliso BR53019-01 is a front vented disc brake rotor engineered as a direct OE-replacement unit. Manufactured from full-cast iron, this rotor delivers consistent stopping performance and long service life. The vented construction promotes efficient heat dissipation, helping to reduce brake fade during repeated or heavy braking.

The rotor features a non-directional swirl finish on the braking surface, which is precision-balanced for smooth, vibration-free operation and eliminates the need for bench machining prior to installation.

Key Features:

• Vented rotor design for improved heat dissipation and reduced brake fade
• Full-cast iron construction for durability and consistent friction performance
• Non-directional swirl finish — ready to install, no pre-machining required
• Conventional (non-drum-in-hat) rotor design
• Non-directional braking surface for even pad wear and seating
• 5-lug bolt pattern with 5.00 in. bolt circle diameter
