I may be mistaken but when you work on someones brakes, could you not be held liable if something where to fail because of your workmanship, I know they sell them for do it yourselfer's but..

I do my own brakes, families, and the GF's, but I don't think they will go after me for it.

I never open the bleeder screws just crack them so they will work. I just remove the brake fliud resorvior cap & force the piston back in the bore before I remove the caliper making sure the resorvior dosn't overflow.
