The Seal Kit, brake caliper (11.0441-4811.2) restores smooth movement of the brake caliper, ensuring even pad pressure and reliable braking. Replacing worn sleeves improves brake performance. Use Porza’s smart search to find the correct set.
A brake caliper seal kit is a collection of sealing components used to restore the hydraulic integrity of a brake caliper. It typically includes piston seals (pressure seals), dust boots, retaining rings, and sometimes additional O-rings or protective caps. These components ensure proper sealing of brake fluid, protect internal parts from contamination, and maintain smooth piston operation within the caliper housing.
Key specifications include seal dimensions (inner diameter, outer diameter, and groove fitment), material type (usually EPDM rubber), and compatibility with brake fluid types such as DOT 3, DOT 4, and DOT 5.1. The materials must withstand high temperatures (typically 150–200°C or higher), pressure fluctuations, and exposure to moisture and chemicals. Precision manufacturing is critical to ensure proper sealing and long-term durability.
A seal kit should be used during brake caliper overhaul or when there are signs of fluid leakage, sticking pistons, or reduced braking performance. It is also recommended as preventive maintenance when rebuilding older or high-mileage brake systems to restore optimal hydraulic function and reliability.
Porza offers a fit guarantee option where your vehicle details, such as license plate or VIN, are checked against product specifications. This ensures the seal kit matches your exact brake caliper type and piston dimensions, minimizing 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 flexibility and 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.
