Just curious: Are replacement cylinders not possible to find anymore? What about taking you brake cylinders to a professional rebuilder? Would they have better tools and parts for a rebuild?
I haven't had brake problems on my coupe yet(knock and wood), but I recently started driving it more regularly. It was in storage with the previous owners for a long time and I wouldn't be surprised if I get a little fluid leak some time this summer.
Although on a Honda 600, the brakes don't really have to do a whole lot of work. The car barely weighs over 1000 pounds, if that.
