Review on ACDelco 17801B Professional Bonded Brake by Gary Zielinski

2006 Corolla LE Installed in July with new drums, cylinders and fasteners. It is now October and one shoe appears to be defective with a discolored spot. Loud noise when warming up. I expected more and don't think I'll get product support from Revain at the moment. Going forward I will only buy from my local parts store as I have been told that you can swap out noisy pads/shoes if something is clearly wrong (as in this case). Even if I run my fingernail over a normally colored part of the shoe, it slides smoothly. The discolored area is rough.
