About Centric Premium Semi-Loaded Disc Brake Calipers

The Centric Premium Semi-Loaded Disc Brake Calipers line offers a balance between fully loaded and bare calipers by including essential components such as the mounting bracket, abutment clips, and bleeder screw. This semi-loaded design simplifies installation while allowing users to reuse existing brake pads if desired. The 141.66504 caliper benefits from this approach, providing a reliable replacement option for various GM vehicles without the need for additional hardware purchases.

Detailed Product Description

This disc brake caliper features a durable aluminum casting (casting number K244079c) that reduces unsprung weight and resists corrosion. The single 54mm phenolic piston helps minimize heat transfer to the brake fluid, reducing the risk of vapor lock and improving brake feel. The caliper’s inlet thread diameter is M10x1.0, compatible with standard banjo fittings, and the bleeder screw also uses an M10x1.0 thread, facilitating proper brake system bleeding. The gray finish provides a neutral appearance suitable for most brake assemblies. Included mounting brackets and abutment clips ensure proper alignment and secure installation, although mounting hardware bolts and brake pads are not included.
