The brake pads and jaws get contaminated with dust and the like,making them stick a little. My guess is they get disassembled before test and cleaned perfectly.

How much benefit is it, wonder if having a small compressed air squirter - like a headlight washer - would pay off (in terms of fuel savings) or not.

Would be interesting to know what designs of pads/jaws dissipate the contaminants better?
