Product Details

This DFC brake master cylinder is built with a cast iron housing, a strong material that resists corrosion and maintains its shape under pressure. It's designed to replace the original master cylinder on a range of BMW 3 Series models from the late 90s and early 2000s, including the 323i, 325i, and 328i. A properly functioning master cylinder is crucial for your braking system; it's the component that converts the force from your brake pedal into hydraulic pressure, pushing brake fluid to the calipers or wheel cylinders to slow your vehicle.

When your original master cylinder starts to wear out, you might notice a spongy brake pedal, a longer stopping distance, or even brake fluid leaks around the unit. Replacing it with a well-built unit like this DFC cylinder helps restore your braking system's performance and reliability. This part fits directly into the factory location, making installation straightforward for a mechanic.
