Something is not right. You will probably have to take them apart and
find out what it is. Maybe the rotors were still contaminated, maybe you
got something on the pads during your install...maybe the pads never bed in
properly and became glazed...
Take them apart, you should find something pretty obvious..The pads could
really be junk, too....I'd get a good brand pad...especially with an auto
tranny and a Westie with a full load, you are asking those brakes to do
significant work...they aren't the best to begin with and if the pads are
'sub-standard'....
