    Control Element, parking brake caliper

     The Control Element, parking brake caliper (STA1784) provides secure mechanical locking for the parking brake system. Replacing a worn caliper restores strong holding force and ensures safe parking performance. Use Porza’s smart search to find the correct caliper.  

    FAQ

    A control element in a parking brake caliper is an internal mechanical component that regulates the activation and adjustment of the parking brake mechanism. It works together with the lever, spindle, and adjuster system to convert the cable input into controlled piston movement. This ensures that the brake pads are pressed against the disc with the correct force when the parking brake is engaged.

    Key specifications include dimensional accuracy, compatibility with the caliper’s internal mechanism, and material quality. Control elements are typically manufactured from hardened steel or precision-machined alloys to withstand mechanical stress and repeated use. They must operate reliably under high temperatures (often exceeding 150–200°C) and resist corrosion from moisture and brake fluid exposure. Precise tolerances are essential for smooth and consistent operation.

    Replacement is necessary when the parking brake mechanism becomes unreliable, such as inconsistent holding force, sticking components, or failure to engage or release properly. It is commonly replaced during a brake caliper overhaul or when internal wear or corrosion affects the performance of the parking brake system.

    Porza offers a fit guarantee option where your vehicle details, such as license plate or VIN, are checked against product specifications. This ensures the control element matches your specific brake caliper design and internal configuration, reducing the risk of incompatibility.

    Porza provides high-quality brake components with fast shipping across Europe. Customers can order online or choose in-store pickup in the Netherlands, Germany, or Belgium. This allows both professional workshops and individual users to quickly access the correct parts when needed.

    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 reliable and risk-free purchasing experience.
