Well my brakes went soft on me before I even left town, but I'm sure driving through the mountains didn't help. I agree that the problem may come back, this week I'm gonna drive it a few times and keep a close eye on everything. I couldn't find any signs of leaking, but my brake fluid must have gone somewhere.
The line going to the passenger's rear tire had the most air in it, so I would suspect something along that side first. Sometime this year I'd still like to redo my brakes and replace everything: booster, master cylinder, pads, rotors, shoes, wheel cylinders, hoses. They're all of questionable age.
