    Brake pads aren't typically much thicker than a penny when new, new pads for my Hope Mono 6 calipers are .08: thick, new pads for my Hayes are .075" thick. You'll want to replace them before they get down to metal. Also, typically, brake performance will drop off dramatically as the pad nears minimum thickness.

    So when the brakes wear down the piston stick out farther....so they get more prone to sticky piston disease.....

    When the get down to about 15% of where they started....if you ride through some tough going muddy rainy conditions you can lose that layer in a single ride....

    So if you notice a lot of sticky piston problems draggy brakes, check the pads, or if you think you might get into some mud etc check the pads.....
