I'm presently swapping out Wheel Cylinders due to leakage caused by a small amount of rust in the bottom of the bores. I discussed the possibility of sleeving the cylinders with my machinist, and he brought up the possibilty of honing them out and bringing them back into spec via chrome or nickel plating. There's a plating shop in the next town, so I'll see if they want to take it on.
This might be a good save for MC's if it works out, because they have various small openings into the cylinder that would make sleeving quite challenging. Most people's brake system leaks result from corrosion from water sitting in the bores of the MC/WC's rather than wear, so this might save general aggravation.
On a related note, I found that the copper washers for the banjo fitting were not available locally, and they were seeping when I reused them. I recalled that heating copper and quenching it anneals (softens) it, so I suspended the washers on a length of wire with a hook, heated them with a propane torch, and dunked them in a bowl of water. Presto- no more seeps! I've ordered new ones- they don't seem to come with wheel cylinders anymore- so I'll be able to move the truck with my temporary fix.
