This Bosch QuietCast Disc Brake Rotor 53011421 is used for front brake replacement on 2019-2023 Chevrolet Silverado 1500, 2022 Chevrolet Silverado 1500 LTD, 2019-2023 GMC Sierra 1500, 2022 GMC Sierra 1500 Limited, 2021-2023 Cadillac Escalade, 2021-2023 Cadillac Escalade ESV, 2021-2023 Chevrolet Tahoe, 2021-2023 GMC Yukon, and 2021-2023 GMC Yukon XL. This part cross-references Monroe Shocks & Struts (e.g., 13514522, 13542112) for the same application.
Use this rotor to address brake pulsation from rotor runout, scoring on the braking surface, uneven pad wear, and corrosion-related braking noise. It also serves as a direct replacement when the original front rotor no longer meets thickness specifications.
Installation requires verifying rotor diameter, bolt pattern, center bore, and thickness against the vehicle’s front brake setup before service. Clean the hub mounting surface, inspect pads and calipers, and confirm the directional brake surface is installed correctly for the application.
Bosch QuietCast brake components are built for OE-style replacement needs and consistent fitment across supported applications. Confirm vehicle-specific brake measurements before installation to ensure proper front rotor selection.
