I worked with 3 guys who each worked several years at a restoration shop who specialized in installing brass sleeves. None of the three had anything good to say about the results. They not only saw many failed cylinders returned, but had to use brass sleeved cylinders on the restorations they were involved with, and have experienced the problems first hand.
The problems were:
leaking cylinders.
Sticking cups, causing brakes that don't engage and cars that run in to things. for some reason the seals will sometimes want to stick to the brass.
corroded cylinders.
Cylinders that wear prematurely, as the brass is soft.
The same guys now use Mark, mentioned above, and have never had a problem with any of his cylinders. I have seen about a dozen cylinders he installed sleeves in, and I am very impressed with his workmanship, I am also a machinist.
