Using this brake kit is easy. First, install the master cylinder, brake caliper, floating brake disc, and connect the brake line according to the instructions. When using, make sure to check the brake fluid level regularly. Also, keep an eye on the wear of the brake pads. For maintenance, clean the brake components periodically to remove dirt and debris. And remember, the brake disc hub is sold separately, so if you need it, purchase it separately. Always follow safety rules when working on your brakes.
