This high - quality OTK rubber seal is specifically designed for the front brake calipers of BS3 and BS4 models. It provides a reliable seal to prevent brake fluid leakage and ensure smooth braking performance.

Using this seal is easy. First, make sure your hands are clean to avoid any dirt getting into the brake system. Remove the old seal from the front brake caliper of your BS3 or BS4 model gently. Then, carefully place the new seal in its position. When installing, be gentle to prevent any damage to the seal. As for maintenance, regularly check the seal for signs of wear or damage. If you notice any cracks or leaks, replace the seal right away. Also, keep the brake caliper area clean to extend the life of the seal.
