Product Details

This is a DFC brake master cylinder, part number 355-31058. It's a direct replacement for the original unit on a wide range of BMW models, including the 2014-2016 BMW 228i, the 2012-2014 BMW 328i, and the 2014 BMW 428i, among others. The master cylinder is the heart of your car's hydraulic braking system; it converts the force from your brake pedal into hydraulic pressure that pushes the brake pads against the rotors, slowing your vehicle down.

When your master cylinder starts to wear out, you might notice a spongy brake pedal, a longer stopping distance, or even brake fluid leaks. This DFC master cylinder is built to meet the original equipment specifications for your BMW, ensuring it will fit right and function correctly. It's made from durable materials to withstand the rigors of daily driving and the heat generated by the braking system, helping to restore your car's stopping power and safety.

Replacing a master cylinder is a job that requires careful attention to detail, especially when bleeding the brake lines afterward to remove any air. If you're experiencing issues with your braking system, this DFC master cylinder is a solid option to get your BMW back to performing as it should.
