Power Brakes reconditions and restores just about every make and model of brake cylinder, irrespective of age or condition.
, its expensive but probably cheaper than a new one from merc.
rebuilding them is a nice simple job, just be carefull when you pull the rubber boot back as the pins can ping out.
westfield are a good company, never used vk but their prices seem reasonable.
