Product Details

The DFC GEOSPEC Coated Rotor line focuses on coated brake rotor applications where surface protection and consistent fitment matter. This rotor is specified as a vented front disc brake rotor and is listed for 2013-2019 Cadillac XTS front applications with 5 lug wheels, excluding Coachbuilder Limo models, as well as 2014-2017 Buick Regal front applications. The 604-45019 rotor uses the listed dimensions to match the original brake setup on those vehicles, making it a direct replacement choice for front brake rotor service on Cadillac XTS and Buick Regal models.

This part number 604-45019 is a fitment-specific rotor for drivers searching for a front brake rotor for 2013-2019 Cadillac XTS or a front disc brake rotor for 2014-2017 Buick Regal. The coated surface helps protect non-friction areas of the rotor, while the vented design supports front brake cooling in normal road use.

What It Helps Address

• Brake pulsation caused by a worn or uneven front rotor
• Reduced braking performance from rotor wear beyond discard thickness
• Corrosion on rotor surfaces and hat areas
• Noise or vibration related to rotor condition
• Front brake service needs on Cadillac XTS and Buick Regal models

Installation Notes

• Verify front axle fitment before installation.
• Confirm 5-lug wheel configuration on Cadillac XTS applications.
• Check rotor thickness against the 27 mm discard thickness before reuse decisions.
• Inspect pads, calipers, and hub surfaces during brake service.
• Clean the rotor and hub mating surfaces before installation to support proper seating.

Quality Assurance

Dynamic Friction DFC GEOSPEC Coated Rotor components are built to match the listed vehicle applications and dimensional requirements for front brake service. Part number 604-45019 is specified for 2013-2019 Cadillac XTS and 2014-2017 Buick Regal front fitment.
