The brake system needs to be inspected and rebuilt in its entirety. That means all seals, pads, flexible lines, fluid, damaged steel lines, and so on, will need to be fixed or replaced. If your rotors are excessively cracked or worn too thin, inquire as to the latest technology for these items from your brake manufacturer. Rotor failure is always serious. Oil-filled hubs, like the Wintters 007 above, should also be serviced.
