Re: 5000s brake woes

MC is worth looking at, but i would be more concerned about intermittently
seizing calipers.   this would cause both the hard-to-brake and not-releasing
symptoms as well as possibly the notchiness.  and i've seen the exact behaviour
before - brake is hot and seized up, cool down for a little while, then a few
pumps get it to release.

this would also fit the fact that the brakes stick in traffic - when they start
to get hot - yet you were able to drive home 2 hrs. (presumably mostly highway)
without a problem.
