    DIY: Do It Yourself
    I am rebuilding my calipers and the attached image is of one of the pistons. Overall it is in great shape except for the edge near the end of the dust boot. I expect that since it's near the outer edge it should be fine but looking for some confirmation from the forum. I really don't want to...
