Daft question of the morning, to be sure, but could someone confirm for

off-centre, the short end faces the front of the bike, i.e., the toe is
shorter than the heel?


Look at the Park Tools website for images. When you fit the brake
blocks, you put a piece of cardboard/whatever at the rear of the brake
block, so the front part touches the wheel first when braking.
