They metal at the edge of the dust seals on mine was starting to corrode and the dust seals trying to squeeze out siezing the pistons on mine so rebuilt it without dust seals a couple of years ago as a temporary measure to get it through MOT. Got a eBay caliper to rebuild but it was as bad as my one so never rebuilt it. Had no problems running without dust seals and just clean it once a year
