Yeah, I'm thinking you are correct about the master, alas. The brake lines are not likely to be the problem, as I had replaced all the flexible brake lines to the calipers a few years ago with the Goodridge stainless covered lines. And, the anti-brake warning light has stayed off when I drive, indicating that that system is ok. Also, the fuse for that system is fine, so I figure that the warning light being on was just an anomaly, just being on for the one time, as warning lights sometimes do, just because.
So, I figure that the seal for one of the two internal brake fluid systems in the master has allowed fluid to go where it is not wanted, and the right front and left rear system calipers are not fully retracting, esp when the system gets hot in hot stop and go driving, as was yesterday. If I just drive the car just to the supermarket or Lowes, not long drives at all, the brakes don't get that hot, and not wearing the pads all that much, so I will take my time getting this fixed. The car doesn't feel like it has dragging brakes, drives as it has before. Maybe if I just bleed that side circuit a little, the unwanted fluid will drain down a little, for a little while anyway.
I'm not crazy about diving in and replacing the master at this time (I know Steve could do it in 15 minutes, but not I. Of course, will use his written instructions in a different posting from 2006), but first I do have new front discs, pads, and one way bleed fittings to install, to get that over with. Not difficult or messy compared to the master, (too much other stuff to remove, etc). Will wait until warmer weather, Yes, I'm a procrastinator, lol.
