Caliso BR31305-01 Front Vented Disc Brake Rotor with Corrosion-Resistant Coating

The Caliso BR31305-01 is a front vented disc brake rotor engineered as a direct OEM replacement. Constructed from full-cast iron, this rotor delivers reliable, consistent stopping performance and is built to meet the original fit, form, and function requirements of the vehicles it serves.

The -01 designation indicates this rotor features a corrosion-resistant coating applied to the hat and edge, providing lasting protection against rust and premature deterioration — a key advantage over uncoated alternatives, particularly for vehicles with open-wheel designs where the rotor is more visually exposed.

Key Features:

• Vented construction for improved heat dissipation during braking
• Non-directional swirl finish on the braking surface — ready to install without pre-machining
• Rust-resistant coating on hat and edge for extended corrosion protection
• Full cast iron construction for durability and consistent thermal performance
• 5-bolt mounting pattern for precise OEM fitment
• No ABS sensor ring included
• Not cross-drilled or slotted — standard plain rotor design
• Manufactured in an ISO-certified facility to meet strict quality standards
