Hanging rear caliper Bernie says:

[SuffolkD at aol.com]

Bernie et al:
While the E-brake could be the issue, (one side not releasing) there IS a 
proportioning valve for Left vs. Right.  This ALSO could lead to unmatched 
caliper pad wear side to sdie (L&R)
Strangely, the "Valve" is on the right side of the car towards the caliper 
AFTER the "Distributor" #15 in "the family album" PN# 803 611 755, the way its 
drawn, it would seem to only affect the right rear (passenger) side 
caliper.......................
Similarly, the piston when extended far out at near full travel will droop, 
or cock out of alignment.  Seen that one.
