Caliso BR54098-01 Solid Drum-In-Hat Rear Disc Brake Rotor

The Caliso BR54098-01 is a solid, drum-in-hat rear disc brake rotor engineered to deliver reliable, smooth, and safe stopping performance. Constructed from durable cast iron and manufactured to strict tolerances in an ISO certified facility, this rotor is built to meet the requirements of fit, form, and function as a direct OE replacement.

A non-directional swirl finish on the braking surface eliminates the need for machining prior to installation, promotes better brake pad contact during bedding, prolongs pad life, and contributes to quieter operation. The rotor receives a corrosion-resistant coating on the hat and edge for lasting protection against rust and environmental wear. A precision-machined hub hole chamfer ensures a proper hub-centric fit, reducing vibration for smooth, confident braking.
