Product Line Details: Centric Premium Semi-Loaded Disc Brake Calipers
The Centric Premium Semi-Loaded Disc Brake Calipers line provides semi-assembled calipers that include key components such as mounting brackets and abutment clips, but exclude pads and mounting hardware.

Technical Specifications and Features
This disc brake caliper features a 32mm piston diameter made of steel, housed within a cast iron body finished in gray.

Abutment clips and mounting brackets are included to ensure proper installation and secure fitment on the Mazda Miata.
Common Applications and Problem Solving
- Replacement of worn or damaged disc brake calipers on Mazda Miata models

Installation Notes and Tips
Ensure compatibility with your Mazda Miata by verifying part number 141.45549 before installation. The caliper comes with mounting brackets and abutment clips but does not include brake pads or mounting hardware bolts, so these should be sourced separately if needed. Properly torque all mounting bolts and bleed the brake system using the included bleeder screw to remove air and maintain optimal brake performance. Inspect brake lines and fittings for wear during installation.
