Any question answered...

Can anyone please tell me if cantilever pad toe in means toed in towards the front of the bike, or toed in towards the direction the wheel is travelling? I am trying to fix some squealing cantilever brakes on a friends bike, and I can't remember which way the pads should be aligned.

Which way do your toes point when you're on the bike? Now turn them inwards, i.e. heel out. That's toe in. On a brake pad, that actually means that the trailing edge of the pad hits the rim first, because the brake is travelling backwards relative to the rim, so I can see how it might be confusing
