Detailed Product Description

This Centric Premium Semi-Loaded Disc Brake Caliper 141.66039 features a durable aluminum casting that reduces unsprung weight while maintaining structural integrity. The floating caliper design with two steel pistons ensures even pressure distribution across the brake pads, improving braking efficiency and pad life. The caliper includes a bleeder screw with M10x1.0 thread size for easy brake fluid bleeding and maintenance. It comes with the necessary mounting bracket and abutment clips, although mounting hardware and brake pads are not included. The inlet fitting uses a banjo type with a 10 mm thread diameter, compatible with factory brake lines on the specified Cadillac and Pontiac models.

The Centric Premium Semi-Loaded Disc Brake Calipers product line is designed to provide a balance between ease of installation and reliable performance. Semi-loaded calipers come partially assembled, including pistons and seals, which reduces installation time compared to rebuilding a caliper from scratch. This line is suitable for drivers seeking a quality replacement part that meets or exceeds OEM specifications without the need for additional machining or assembly.
