About Centric Premium Semi-Loaded Disc Brake Calipers: Bracket Not Included
This Centric Premium Semi-Loaded Disc Brake Caliper line provides remanufactured calipers that come semi-loaded, meaning they include abutment clips and bleeder screws but do not include mounting brackets or brake pads. This allows for flexibility in installation and compatibility with existing hardware, making it suitable for professional repairs on vehicles like the Cadillac DeVille and Chevrolet Silverado 1500.
Detailed Product Description
The Centric 141.66521NB rear disc brake caliper is engineered for reliable braking on rear axle applications of Cadillac DeVille, DTS, and GMC Sierra 1500 models, including Classic versions and Chevrolet Silverado 1500 trucks. Its aluminum casting reduces weight while maintaining strength, and the phenolic piston helps resist heat and corrosion, contributing to longer service life. The floating caliper design ensures even pad wear and consistent braking force. This caliper features a rust preventative gray finish to protect against environmental damage. Note that this semi-loaded caliper does not include mounting brackets or brake pads, so these components must be sourced separately.
