Technical Specifications and Features
This Centric caliper features a fixed design with four steel pistons, each measuring approximately 1.89 inches (48 mm) in diameter, providing even pressure distribution across the brake pads.

Installation Notes and Tips
Installation of the Centric Premium Semi-Loaded Disc Brake Caliper 141.44306 requires removal of the old caliper and proper cleaning of the mounting surface. Since mounting hardware and brake pads are not included, ensure compatible pads and hardware are sourced separately. The included bleeder screw should be used to properly bleed the brake system after installation to remove air and maintain hydraulic pressure. Verify the inlet fitting matches the vehicle’s brake line specifications before installation. Torque mounting bolts to manufacturer specifications and inspect for leaks after assembly.
