Caliso 6621581 Front Vented Coated Disc Brake Rotor

The Caliso 6621581 is a front vented coated disc brake rotor engineered as a direct OE replacement for select passenger cars and light trucks. Featuring a corrosion-resistant coating applied to the hat, edges, and non-contact surfaces, this rotor resists rust and surface oxidation from the moment it is installed — eliminating the unsightly rust bloom common on uncoated rotors and helping maintain long-term appearance and performance.

The vented two-piece design promotes active airflow between the rotor faces, dissipating heat efficiently under repeated or heavy braking. The friction surfaces are precision-machined and balanced to strict dimensional tolerances, delivering smooth, vibration-free pedal feel from the first stop.
