there is nothing to resleeve on these actually. rubber gasket on master cylinder for shaft from booster to slide in. use socket and impact wrench on the frozen cylinder cover and your likelihood of getting it off ok increases a lot. Also penetrating fluid too of course. one of my 55s has a plastic cap in it!!! not authentic but wonderful.

Been reading all the info re;55 Imp power brakes. I have a 55. Got my master done by White Post Restorations in Virginia. They did a fine job of re=sleeving and restoring at a reasonable price though I've forgotten the exact amount. A word of caution to you who own these cars-the square nut topped cylinder cover WILL RUST SHUT if any moisture is present in your system. When you try to "wrench" it off, the hollow nut will crumble and then you have a real problem!! This happened to me, and I had to drill a hole in the top to replenish the fluid until White rebuilt it. I would suggest turning the cover a few times each year to prevent this from happening-- Ted Blackington
