Using this brake cup seal is straightforward. First, make sure your brake system is clean and free of debris. Then, carefully install the seal onto the master cylinder piston as shown in the diagram. It's important to note that this seal is only for DOT 5 brake fluid, so don't use it with other types of brake fluid. For maintenance, regularly check the seal for any signs of wear or damage. If you notice any cracks or leaks, replace the seal right away to keep your brake system working safely.
