Looks like I can get internals from the dealer, but I can't figure out how the heck to disassemble it.
Here's what I have. AFAIK it's stock. Can't find a '99 parts diagram, so I'm going off a 2000, which I believe is the same. Although the diagram doesn't look much like what I have in my hands...

Not sure when they changed them. My '96 Monster is on the third or fourth seal. The non rebuildable cylinders had this toothed pattern on the visible face that looked like a sprocket.
If it is a rebuildable cylinder you just need to blow some air in through the open bleeder. I don't believe there is a retaining ring. Make sure you catch the spring that's in there. You'll need to hone the cylinder body before reassembling.

Funny, that's all there was to it --blew some air in there and it popped out, spring attached. The seal looks good and I can't get the cylinder disassembled, so hopefully a good cleaning will suffice.
Why does one need to hone the cylinder body? Corrosion or pitting? It looked pretty smooth...
Thanks for the info!
Corrosion typically, usually in the area inboard of the piston...at least on my bikes. Besides, you always should give a new rubber seal a fresh crosshatch pattern to wear in on...and lube the snot out of it with brake fluid on assembly. [thumbsup]
Is the brake fluid to swell the rubber seals?

No. The fluid is to prevent damaging the seal during assembly.
