Erm, I thought coppaslip on the pad backs was recommended to reduce brake squeal? Lately I see some sticky stuff included for this - or is this an efficiency thing?yes, a small amount of anti-seize(not copper grease) on the contact points only of the shoes, and the wings of the pads. nothing on the back of the pads of course, thats pointless and just attracts crap.
all as specified in autodata...
