I wanted to replace the cylinders because they are so dang cheap on my '58. I got them from the local FLAPS for a reasonable price, but I found the castings wouldn't fit properly on the plate. Likewise, the bleeder thread forms were different from my old ones, keeping me form swapping my Speed Bleeders over. All-in-all, the new cylinders were a complete mess.
I honed out the old ones and did a blind feel test. I couldn't feel anything so I moved over the innards from the new cylinder castings to the old ones, and they've worked wonderfully ever since.
With that success, I tackled the master cylinder rebuild job, honing out the cylinder per Red58's guidance. To this day, both the brake cylinder and master cylinder rebuild jobs have been extremely successful.
Give it a shot and be extremely cautious at check-out. I recommend testing it at low speed at dawn's first light.
