Caliso BR901644-01 Front Vented Disc Brake Rotor Cast Iron Non-Directional

The Caliso BR901644-01 is a front vented disc brake rotor engineered to restore reliable, smooth, and safe braking performance. Constructed from durable cast iron with a full-cast design, this rotor is precision balanced and features a non-directional swirl finish that eliminates the need for machining prior to installation, creating better brake pad contact from the start.

The precise hub-hole chamfer ensures a proper hub-centric fit, and detailed castings include extractor and set screw holes where applicable for fast, straightforward installation. The conventional vented design promotes effective heat dissipation during repeated braking cycles, helping to reduce brake fade and extend component life.
