QuietCast Rotor Line Details
Bosch QuietCast brake rotors are built for drivers who want a direct-fit replacement rotor with attention to surface finish, corrosion resistance, and consistent pedal feel. This rotor, part number 53011483, follows that approach with a smooth braking surface, vented construction, and protective finishes that help maintain appearance and service life in everyday driving.
Detailed Description
This Bosch QuietCast Disc Brake Rotor is a conventional, rotor-without-hub assembly replacement for front axle service on select Mazda 3, Mazda CX-30, and Mazda 3 Sport models. The vented iron alloy design measures 295 mm in outside diameter, 25 mm nominal thickness, and 46.5 mm overall height, with a 68 mm center bore and 5 mounting bolt holes on a 114.3 mm bolt circle. The directional brake surface and smooth finish support even contact across the pad face, while the Geomet disc finish, coated hat, and rust-resistant coating help protect exposed surfaces. This part cross-references Monroe Shocks & Struts (e.g., BDWK33251, BEET33251) for the same application.
What This Rotor Helps Address
- Front brake pulsation from worn or uneven rotors
- Brake noise caused by damaged or heat-spotted disc surfaces
- Corrosion on exposed rotor surfaces
- Reduced braking consistency from thickness variation
- Service replacement needs on Mazda 3 and Mazda CX-30 front brakes
