OK, thanks for the advice. Another question: Once the bleeder tank has been filed with the new brake fluid and hooked up through the poly tubing to the master cylinder reservoir, I suspect that there initially will be air in the tubing. So is the idea that this air will initially be forced under pressure through the tubing, reservoir, MC and the first brake line to be bled (i.e., the rear passenger line), and will be bled out when the bleed screw on the caliper is opened up? Or am I completely off base? I guess the other thing is to ensure that the bleeder tank is filled up with an adequate amount of fluid at the start ... probably 1.5 to 2 L of fluid (??) ... so that all lines can be bled without a need to re-fill. Again, any advice is appreciated.

That isn't an issue at all. There is a certain amount of air in the tube, correct, but when you pressurize the bottle and open the bleed screw, its still the same amount of air, so the fluid will travel through the tube and into the resorvoir, and the air will stay on top. 1 liter should be fine, but check it after each caliper, and have a second bottle just in case.
