youll need an 11mm wrench (or 6 point socket to get it cracked loose) for the bleeder screw, and I can recall if its a 12, 13 or 14 mm for the brake line, (I picked up a set of line wrenches from 8mm-19mm and a bunch of 6point wrenches as well, they make certain that you're not gonna strip anything! , then I use a light tap in case there is any oxidation on the bolt/nut in question just to make sure it doesn't strip! nothing worse than trying to remove a round bolt!!! (suppose that's where SAE wrenches can come in handy! lol, ie a 1/2" wrench on a rounded 13mm bolt etc.then replace the bolt, don't even try putting the rounded one back on!
