Detailed Product Description
This Centric Premium Semi-Loaded Disc Brake Caliper 141.45537 is designed as a floating type caliper featuring a single 32mm steel piston. The caliper body is made from cast iron, providing the necessary strength and heat resistance for consistent braking performance. It comes with a mounting bracket and abutment clips, ensuring proper alignment and secure installation on Mazda Miata models. The inlet fitting supports both banjo and open types with a 10mm thread diameter (M10x1.0), while the included bleeder screw has a 7mm thread size (M7x1.0) to facilitate brake fluid bleeding during maintenance. This caliper does not include brake pads or pad wear sensors, so those components must be sourced separately.
About Centric Premium Semi-Loaded Disc Brake Calipers

This approach allows for flexibility in brake system upgrades or replacements while maintaining OEM-level fit and function. The 141.45537 model fits Mazda Miata vehicles and is engineered to meet strict quality and performance standards.
