• Full cast construction using cast iron material for strength and heat resistance
• Vented rotor design to improve cooling and reduce brake fade
• Rust resistant coating to protect against corrosion and extend rotor life
• Directional disc finish with a smooth surface for optimal pad contact
• Outside diameter of 344.7 mm (13.571 inches) and height of 85.0 mm (3.346 inches)

Durable Construction and Performance Features

The BD126457E rotor is made from cast iron with a full cast construction, providing a robust and heat-resistant braking surface. Its vented design allows air to flow between the rotor surfaces, enhancing heat dissipation during braking. The rust resistant coating helps prevent corrosion, which is especially beneficial in regions with wet or salty road conditions. The smooth surface and directional finish ensure consistent pad contact and braking efficiency, reducing noise and vibration.
