Question: The clear plastic/rubber shielding on the outside of a stainless steel braided brake line is needed to keep the line sealed right? So if there was just the stainless steel braid showing, that would leak...right? Im having a damn time with my motomaster after flushing the fluid. I have a vacuum brake pump, and its just pulling tons of bubbles. And I probably pulled like half a bottle through the brake system already. And I replaced the crush washers etc, but I just noticed right next to the master (stock mc), a bit of the shielding is pulled back on the brake line, so I can see the stainless braiding.
