Bosch 53011469 Disc Brake Rotor - Front

Bosch QuietCast Front Brake Rotor

The Bosch QuietCast Disc Brake Rotor, part number 53011469, is a front replacement rotor built for Mazda applications that call for a 320 mm vented disc with a smooth braking surface. It uses an iron alloy construction, Geomet disc finish, and a coated hat with rust-resistant coating to support consistent braking performance and corrosion protection.

Compatible With 2019-2025 Mazda CX-5 front, 2016-2023 Mazda CX-9 front, and 2019-2021 Mazda 6 front. This Bosch QuietCast Disc Brake Rotor 53011469 is a direct-fit, rotor-without-hub assembly for vehicles using a 5-lug, 114.3 mm bolt circle and 68 mm center bore.

Key Features

• Iron alloy construction for stable braking performance
• 320 mm outside diameter with 28 mm nominal thickness
• Vented, conventional rotor design
• Smooth brake surface with directional braking surface geometry
• Geomet disc finish and coated hat finish for added corrosion resistance
• Rotor without hub assembly; bearings not included
• Front-position application for select Mazda models

Product Details

Bosch QuietCast is a rotor line focused on quiet, consistent braking characteristics and durable surface protection. This rotor uses a smooth braking surface and directional surface design to match the intended front brake setup on the Mazda CX-5, Mazda CX-9, and Mazda 6 applications listed below. The Bosch QuietCast Disc Brake Rotor 53011469 is engineered as a conventional vented rotor with a rust-resistant coating, making it a practical OE-style replacement for drivers servicing front brake wear or rotor surface damage.

This part cross-references G61N33251 and TK7833251B for the same application.

Common Reasons for Replacement

• Brake pulsation from rotor thickness variation or surface wear
• Scoring, grooves, or uneven pad contact on the braking surface
• Corrosion on the rotor hat or disc surface
• Reduced braking smoothness during front brake service
• Rotor replacement during pad and brake inspection intervals

Installation Notes and Tips

Verify rotor diameter, thickness, bolt pattern, and center bore before installation. Clean the hub mounting surface thoroughly to help prevent runout-related brake noise or pedal pulsation. Always inspect pads, calipers, and hardware condition during front brake service, and confirm the rotor is installed on the correct front position for the vehicle listed.

Quality Assurance

Bosch QuietCast brake components are built to meet the dimensional and material requirements expected for service replacement applications. This rotor is manufactured with a coated finish and rust-resistant coating to support long-term surface protection in everyday driving conditions.
