Detailed Description
This Dynamic Friction rotor is engineered as a front brake replacement for vehicles that use a vented rotor with the listed dimensions and bolt pattern. The coated surface helps protect non-friction areas from rust buildup, which is especially useful on vehicles that see frequent stop-and-go driving or exposure to wet road conditions. If you are replacing worn front rotors on a Chevrolet Impala, Buick Lucerne, or Cadillac DTS, part number 604-46022 matches the specified OE-style dimensions for the application.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Front brake pulsation caused by rotor wear or thickness variation
- Brake noise related to uneven rotor surfaces
- Corrosion on the rotor hat and non-friction areas
- Reduced braking consistency from worn front rotors
- Service replacement needs on Impala, Lucerne, DTS, Allure, and LaCrosse front brake systems
Installation Notes and Tips
Verify rotor dimensions, bolt pattern, and front axle fitment before installation. Clean the rotor friction surfaces and hub mating area during service to help prevent runout issues. Always inspect pads, calipers, and hub condition when replacing front rotors on 2012-2013 Chevrolet Impala, 2014-2016 Chevrolet Impala Limited, 2006-2011 Buick Lucerne, 2006-2011 Cadillac DTS, and 2008-2009 Buick Allure or LaCrosse.
Quality Assurance
