If your Mini is rusty below it is a good idea to check your metal brake lines; rust on them could be disastrous. This complete kit is available, in non-corroding copper, to replace every hard line. They're pre-made in the proper lengths, with fittings in place. Diagonal split system with 4 way failure switch had different pipes/unions. See
