What does a brake master cylinder do?

The master cylinder converts the mechanical force from your brake pedal into hydraulic pressure. This pressure is then sent through the brake lines to actuate the brake calipers or wheel cylinders, slowing your vehicle.

Why is the cast iron housing important?

Cast iron is a strong and durable material that can handle the high pressures generated within the braking system. It helps ensure the master cylinder maintains its integrity and function over time.

Does this master cylinder come with brake fluid?

This DFC brake master cylinder does not include brake fluid. You will need to purchase the appropriate type and amount of brake fluid separately and bleed the brake system after installation.

Product Details

This DFC brake master cylinder is built with a cast iron housing, a material chosen for its strength and ability to withstand the pressures involved in your braking system. It's designed to be a direct replacement for the original part on your 2008-2013 BMW 128i, meaning it should fit right into place without needing modifications.

A properly functioning master cylinder is crucial for your car's safety. It's the component that converts the force you apply to the brake pedal into hydraulic pressure that pushes the brake pads against the rotors. If yours is leaking or not building pressure, you'll notice a spongy pedal or reduced stopping power. This DFC unit aims to restore that critical function, helping to ensure reliable braking performance.

This part is noted to comply with California Proposition 65 warnings.
