HYDROLASTIC WITH SERVO and includes 2 front wheel cylinder bridge pipes if required. You'd think that the way Minis leak oil they'd never rust on the underside, but they do! 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-nickel, to replace every hard line. They're premade in the proper lengths, with fittings in place. Just bend them to the proper shape and install! Single line kit.
