Detailed Product Description
This Centric Premium Brake Master Cylinder 130.45803 features an aluminum construction that provides strength and corrosion resistance, essential for maintaining brake system integrity. The plastic reservoir is designed as a single, removable unit, allowing for easy maintenance and fluid checks. With a bore diameter of 0.875 inches (22.225 mm), this straight bore master cylinder is engineered to deliver precise hydraulic pressure to the brake system. The part includes a master cylinder cap but does not come with mounting hardware, brake booster, push rod, or bleeder hoses, so these components must be sourced separately if needed.
The primary and secondary outlet ports both have M10-1.00 thread sizes, with the primary outlet featuring an inverted flare and the secondary outlet a bubble flare, ensuring compatibility with standard brake line fittings. The unit mounts securely with two mounting holes, providing a stable fit within the brake system of the Mazda Miata.
