excellent, yes.

no, they are pulling the ebrake "arms" on the calipers through full
motion, to the point where it is impossible to pull the "arms" any
further forward.

did not measure it.  i assumed that since the shop did not replace the
rear rotors (just the rear pads) that the thickness was OK.  I guess i
need to buy a measurement tool and do that.

i don't remember reading that in the Bentley while doing the procedure.
i will double check, and get back to you, but i doubt that's in there.

where do the rear lines run?

hmmm.........
no, the braking power has significantly decreased, to the point where i
don't feel the stopping distances are safe.  in addition, your
explanation, although reasonable, doesn't account for the failure of the
e-brake mechanisms.

humored and helped!  thanks, shawn

PS------>any thoughts on my theory regarding proportioning valves ie:the
proportioning valves have failed or are clogged & are not sending enough
pressure to the rear brakes (while the front operation seems fine).  the
Bentley says that failed proportioning valves are usually spotted by
pulling left & right, not necessarily differential from front to rear.
however, it seems that there could possibly be a loss of pressure to the
rear lines/calipers.
