Bosch 53011702 QuietCast Disc Brake Rotor Vented, Coated Iron Alloy

The Bosch QuietCast 53011702 is a premium vented disc brake rotor engineered for reliable, quiet stopping performance. Constructed from iron alloy with a smooth brake surface, this conventional rotor features a rust-resistant coating on both the disc and hat to protect against corrosion and extend service life. Bosch developed the QuietCast line using 3D laser measuring and repeated inspection to deliver tight dimensional tolerances — the kind of precision that matters for confident braking. With Bosch braking components found on one in three Asian, domestic, and European vehicles on North American roads, this rotor reflects the same engineering standards used in original equipment applications.
