    Brake Master Cylinder

    The Brake Master Cylinder (PML430) generates the hydraulic pressure needed for strong and consistent braking performance. Replacing a worn master cylinder restores firm pedal feel and safe, reliable brake operation. Use Porza’s smart search to find the correct unit.



    FAQ

    A brake master cylinder is the central hydraulic component of the braking system that converts the force from the brake pedal into hydraulic pressure. This pressure is distributed through the brake lines to the calipers or wheel cylinders, activating the brakes at each wheel. It ensures balanced and responsive braking performance across the entire vehicle.

    Key specifications include bore diameter, number of circuits (single or dual circuit), reservoir capacity, mounting configuration, and connection types for brake lines. Brake master cylinders are typically made from cast iron or aluminum, with internal seals made from EPDM rubber compatible with DOT 3, DOT 4, or DOT 5.1 brake fluids. They must withstand high hydraulic pressures (often exceeding 100 bar) and operating temperatures typically above 150–200°C.

    Replacement is necessary when there are signs of internal or external fluid leakage, reduced braking efficiency, a spongy or sinking brake pedal, or inconsistent pressure. Internal seal wear or corrosion can lead to loss of pressure and compromised braking safety. In such cases, immediate inspection and replacement are recommended.

    Porza offers a fit guarantee option where your vehicle details, such as license plate or VIN, are checked against product specifications. This ensures the brake master cylinder matches your exact vehicle configuration, including connection types and system requirements, reducing the risk of incorrect fitment.

    Porza supplies high-quality brake components with fast delivery across Europe. Customers can order online or choose in-store pickup in the Netherlands, Germany, or Belgium. This provides quick and flexible access to essential parts for both professional workshops and individual users, with reliable European-wide shipping.

    If you select the fit guarantee, Porza verifies compatibility before shipment. If the product does not fit or meet expectations, it can be returned according to the return policy. This ensures a secure and risk-free purchasing experience.
