Make sure these pins are properly cleaned with a wire brush or Scotch pad, and you can clean out the pin bore (cavity) in the caliper hanger with a wire bristle bottle brush (sometimes referred to as a gun-cleaning brush). Really bad rust and corrosion in this cavity can be cleaned out with a drill bit just slightly smaller than the bore size of the pin. Simply run the drill bit down into the hole by hand to help loosen up some of the caked on rust and gunk, then rinse out with brake parts cleaner. Once done, re-apply brake lubricant to the pin and bore.
What is the purpose of brake wear indicator?
Most brake pads come with mechanical wear indicators that serve one purpose; to notify you that it is time to change your brakes.
