Caliso BR901032 Vented Front Disc Brake Rotor Plain Cast Iron - 11.81in

The Caliso BR901032 is a vented front disc brake rotor engineered to deliver reliable, smooth, and safe braking performance. Constructed from high-strength cast iron and manufactured to strict metallurgical standards (SAE J431), this rotor provides a direct-fit replacement with no machining required before installation.

The rotor features a non-directional swirl finish that creates optimal pad-to-rotor contact right out of the box, promoting even break-in, extended pad life, and quieter operation. A precision-machined hub hole chamfer ensures a proper hub-centric fit, and detailed castings include extractor and set screw holes where applicable for straightforward removal and installation.
