Default Brake & Bose Amp problem

I have a 1993 Corvette with a small brake fluid leak. The leak is where the master cylinder bolts onto the booster.

Is this a leak from the master cylinder or booster? I really don't want to replace the wrong part.

Also, when it's below 40 degrees outside, I end up with air in the brake lines. I only bleed the front driver's side to remove the air. I really don't understand how bleeding the one side gets the air out. Also why does it only suck air when it's cold. Could a master cylinder be causing this.

I also have a problem with something draining the battery. I think it's the Bose amps. If I let the car sit for a couple of days it will not start. If I plug in a charger I can hear a loud humming sound from the speakers. I checked the fuses and found after removing the LC fuse the humming stops. This fuse controls the power antenna and the amp, although, it's marked LC. I would think that when the ignition is turned off, so should the power to the amps, but this isn't the case.

Thanks for any help on these problems......... :cry

Easy fix for the Bose = battery cut off switch. It disengages the battery with a flip of a lever. Also disengages the alarm and the presets. Another good option is to replace it with aftermarket. I don't know how to fix it though. It should turn off with the ignition.
