Product Emphasis: OEM-grade brake master cylinder engineered to convert brake pedal force into hydraulic pressure, transmitting it through the brake lines to the calipers and wheel cylinders. This complete assembly includes the reservoir and internal seals, providing a direct-fit solution for worn or leaking original units. It is a direct replacement for the original master cylinder, which commonly develops internal seal failure or external leaks, causing a spongy pedal, brake fluid loss, or reduced braking performance .
