Re: Readjusting brake lines - rebleed necessary?
Loosen any part of the hydraulic lines that see pressure, (with possible exception to the bleed valve,) and you'll need to bleed. Any liquid that escapes must be replaced with something, and that will be air. When you do bleed, be sure not to over-tighten the caliper bleed valves or may run into problems with sealing. Look up your torque specs. IIRC the master cylinder bolt you're referring to might be 22 ft-lbs.
