Caliso 120-42109 E-Coated Premium Disc Brake Rotor

The Caliso 120-42109 is a premium E-coated disc brake rotor engineered as a direct OE replacement. Featuring a durable black electrocoating (E-coat) finish applied electrostatically across the entire rotor surface, this unit delivers significantly superior corrosion protection compared to standard phosphate-coated rotors.

Key Features:

• Black E-Coat Anti-Corrosion Finish: Electrostatically applied coating designed to withstand prolonged exposure to moisture and road salt, providing long-lasting protection well beyond basic phosphate finishes
• Double Disc Ground Friction Surface: Precision grinding ensures the front and rear friction faces are perfectly parallel, reducing rotor runout and minimizing brake noise and vibration
• Non-Directional Finish: The machined surface finish shortens pad bed-in time and promotes even pad wear from the first use
• Symmetric Vane / Split-Core Casting: Vane geometry promotes uniform heat distribution across the rotor during heavy braking, reducing the risk of warping and fade
• OE-Style Design: Matches original equipment specifications for a straightforward, no-modification installation

The 120-42109 is sold as a single rotor. Always replace brake rotors in axle pairs and inspect or replace brake pads at the same time to ensure balanced, safe braking performance.
