Hi guys I'm going to be spraying the calipers on my B7 S4 in red. Now, I'm confident in removing them - there's just one niggly thing that concerns me and hope you can help me out. What should I use to pinch off the rubber brake lines when I remove them? This is the rubber line that connects between the caliper and the body of the car (where it attaches to the metal pipework). The hoses seem REALLY tough (are they metal lined or something???). I have some plastic brake pipe clamps but they are noweher near strong enough to pinch these pipes! Can you go hard on them (i.e. mole grips) without damaging them? Looks like it will take a LOT of pressure to clamp these and really worried about damaging the lines. Finally (excuse my lack of knowledge - keen and capable newbie!) but once pinched off, removed, cleaned and sprayed I assume there will then be air in the system when I connect it back up. Is the nipple for releasing air?? If so, how? Thanks guys!
