i just reread your posts in this thread and i have a couple questions for you. you think you have a problem with the rear brakes due to the rears operating at a cooler temp than the fronts and because the brakes are generally "crappy" in feel, correct? aside from the temp difference, what leads you to think the rears are the guilty party?
what i mean is... the brakes on my new tour check out as being in fine shape even though they aren't as effective as those on my last csvt, an early 99. i happen to know the difference between the two cars is due to better front pads, braided steel lines and fresh properly bled pretty ok fluid. since you have already maintained/repaired/replaced the rear parts you may want to expand your search. just a thought.
