I've had my Jeep a long time, several years ago I started doing the following.
Whenever anything in the brake system needs replaced, I pull everything but the booster, proportioning valve, and the lines. The MC, Calipers, cylinders, pads, and shoes all come off. On my Jeep, all of these have a lifetime warranty so all it costs me in the end is new fluid. All this can be done easily in an afternoon and it'll stop like it did when it was new afterwards.
(I should probably feel bad for bringing back parts that aren't shot, but for what I had to pay for my first MC, I don't.)
