    Wheel Brake Cylinder

    The Wheel Brake Cylinder (LW31771) applies hydraulic force to the brake shoes for safe and balanced drum braking. Replacing a worn cylinder restores full braking performance. Use Porza’s smart search to find the correct cylinder.

    FAQ

    A wheel brake cylinder is a hydraulic component used in drum brake systems to convert brake fluid pressure into mechanical force. When the brake pedal is pressed, hydraulic pressure pushes the internal pistons outward, forcing the brake shoes against the drum to create friction and slow the vehicle. It is a key part of ensuring effective and balanced braking performance.

    Key specifications include cylinder bore diameter, number of pistons (typically two), mounting configuration, and connection type for the brake line. Materials are usually cast iron or aluminum for strength and heat resistance. Internal seals are made from EPDM rubber, compatible with brake fluids such as DOT 3, DOT 4, and DOT 5.1. The cylinder must withstand hydraulic pressure and operating temperatures often exceeding 150–200°C.

    Replacement is necessary when there are signs of brake fluid leakage, corrosion, or piston seizure. Symptoms include reduced braking performance, uneven braking, or fluid visible around the drum area. In some cases, a repair kit can be used, but severe wear or damage requires full replacement of the cylinder.

    Porza offers a fit guarantee option where your vehicle details, such as license plate or VIN, are checked against product specifications. This ensures the wheel brake cylinder matches the correct bore size, mounting type, and connection for your braking system, reducing the risk of incorrect fitment.

    Porza provides 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 allows 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.
