(sorry, I meant for this to go in the Mechanics forum...)
just bought a new pair of Shimano Deore brake pads, for a Linear Pull caliper setup. As a novice, I carefully followed the Park Tools 'Big Blue Book' instructions to install the new pads. The right pad is set very nicely. However, the left pad is very excessively "toed-in" -- i.e., the front of the pad is rubbing the rim, while the back is not even close. The pad is at probably a ~15-20 degree angle away from the rim.
What might I be doing wrong here? I've re-adjusted the nuts/washers on that side, several times, but the pad ends up in the same (mis)alignment. Would installing the pad with a shim at the front help? Is it possible that the pad is defective / warped?
