Product Details

DFC is known for making well-built replacement parts that get your vehicle back on the road. This brake master cylinder is designed for your 2002-2004 or 2006 Hummer H1, helping to ensure your brakes respond when you need them to. A master cylinder is a critical component in your braking system, converting the force from your brake pedal into hydraulic pressure that activates your brakes.

This unit is built to meet the original specifications for your Hummer H1, meaning it should fit right and function as expected. When your master cylinder starts to wear out, you might notice a spongy brake pedal or a longer stopping distance. Replacing it with a new one like this DFC unit can restore that firm pedal feel and improve your confidence behind the wheel.

This master cylinder is a direct replacement part. Always refer to the manufacturer's installation instructions for proper bleeding and setup procedures to ensure optimal brake performance.
