Detailed Product Description
This Centric Premium Semi-Loaded Disc Brake Caliper 141.66030 is engineered to meet the braking needs of Buick Aztek and Pontiac Rendezvous vehicles. The caliper features a cast iron body that provides structural integrity and long service life. It uses a single phenolic piston measuring 64mm in diameter, which helps reduce heat transfer to the brake fluid, improving overall braking consistency. The floating caliper design allows for smooth pad engagement and even wear.
The caliper comes semi-loaded, meaning it includes the mounting bracket and abutment clips but does not include brake pads or mounting hardware. The inlet fitting is a banjo type with an M10x1.5 thread diameter, compatible with standard brake lines. A bleeder screw with M10x1.0 thread size is included to facilitate proper brake system bleeding during installation or maintenance.
