    Repair Kit, brake caliper

    The Repair Kit, brake caliper (D41666K) restores proper brake caliper function by replacing worn internal components. It ensures smooth piston movement, consistent braking pressure, and extended caliper lifespan. Use Porza’s smart search to quickly find the correct repair kit for your vehicle using your license plate, VIN, or detailed vehicle information.  

    FAQ

    A brake caliper repair kit is a set of components used to restore the functionality of a worn or leaking brake caliper. It typically includes piston seals, dust boots, retaining rings, O-rings, and sometimes guide pin components or grease. These parts are essential for maintaining hydraulic pressure, protecting internal components, and ensuring smooth piston movement within the caliper housing.

    Key specifications include seal dimensions (inner and outer diameter), compatibility with piston size, and material quality. Most seals are made from EPDM rubber, resistant to brake fluids such as DOT 3, DOT 4, and DOT 5.1, and capable of handling temperatures above 150–200°C. Precision fitment is critical to ensure proper sealing, pressure retention, and long-term durability.

    A repair kit should be used when there are signs of brake fluid leakage, sticking pistons, reduced braking performance, or visible wear inside the caliper. It is commonly used during brake caliper overhaul to extend the lifespan of the original caliper and restore proper braking function.

    Porza offers a fit guarantee option where your vehicle details, such as license plate or VIN, are checked against product specifications. This ensures the repair kit matches your specific brake caliper type and piston dimensions, 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 allows quick access to essential parts for both professional workshops and individual users.

    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.
