I'd check brake centering, too. Wear should be symmetric between brake pads on a given wheel.Originally Posted by cheetahmk7 .
I shall have a look when I get my bike back. (Unfortunately my frame didn't last as long as the pads or rims, having just cracked)

Learning to brake properly (for emergency stops or fast downhill corners) means learning that lesson and putting it into practice.
Yes, the question was about how to reduce wear. So?Originally Posted by An old Guy .
The question was how to prevent wear of the braking surface.

( I will slur a few terms to keep this simple.) Dynamic (sliding) friction has a single value. Static friction has a range of values from 0 to a maximum. The maximum of static friction is larger than the value of dynamic friction. But in general, the static friction values used by bicyclists - including racers, is less than the dynamic value.
Proper braking depends on what you want to accomplish. I don't recall ever having my braking approach the deceleration of a locked wheel except as the bicycle comes to a stop. In that case the tire does not skid. I guess you have different needs.
Would furniture polish or car wax be ok?Originally Posted by kdelong .
Strickly reducing wear? You could grease them but that would attract dirt and probably act like grinding compound. Therefore you would want to use a good dry lube.
Try to stay on the subject of the question. I do.Originally Posted by alienator .

Maximum braking on a bike occurs at the point when the bike starts to rotate over the front wheel. You'll note that when that happens, the front is not locked. After that point, the braking force cannot be increased because it would just increase the angular velocity of the bike around the front wheel's axle.
