Bosch 53011528 QuietCast Premium Disc Brake Rotor - Geomet Coated, Directional

The Bosch QuietCast 53011528 is a premium rear disc brake rotor engineered for consistent, confident stopping performance. Built from iron alloy with a Geomet-coated disc surface and a coated hat, this rotor delivers excellent corrosion resistance right out of the box — helping it maintain appearance and function even in harsh driving conditions. The brake surface is smooth and directional, and the rotor is a conventional solid construction. Bosch developed the QuietCast line using 3D laser measuring and repeated inspection to raise the bar on aftermarket rotor technology, making it a trusted choice for technicians working across all makes and models.
