Master looks rebuildable no problem, just will take time to clean it all up. Brake cleaner will dissolve most of that gunk, and a little scraper and elbow grease will get the rest.

The slave, it will depend on if the walls of the cylinder are still smooth or not. They usually clean up well, but there looks to be some rust in there as well, and that can score the walls. Again, brake cleaner and some steel wool should clean it up.

For parts, I ordered this kit from amazon for the master, but as my review on Amazon shows, there is a washer missing from the kit that you will need to reuse or buy another one.
Otherwise kit is fine.

For the slave, I ordered my parts from a local dealer. price was competitive from what I could get it for online and had it next day.

Admin has a how to video with part numbers needed HERE

For the clutch line, you may be OK as is, but you may want to spray some brake cleaner down it to clear it out as well, then some compressed air, and bleed it through a few times to make sure the line is clear.

I plan to remove the master and use my pets washer to clean it all out, the slave I'm not 100% sure on. I'll order that kit and go see my local dealership for the slave

They just press in with a seal. Honda has a repair kit for them.

Yeah, I have seen replacements on e-bay for like $15.

Just press out old one and clean up mounting area, then install new one.

Here is a video showing a brake master, but clutch is the same.

Interesting to see how he used a socket on the inside to remove, most people take a screwdriver and punch it out, and it usually ends up breaking, but this seems to push it out whole. Same for the install, using a c-clamp with a piece of flat metal (although a socket would probably work as well) is an interesting way to install.

edit: quick search found this kit on ebay: https://www.ebay.com/itm/253765271448

there may be others cheaper, this was just the first I found.

another edit, found this on amazon, cheaper and includes 2 sight glass pieces (in case your brake master needs replacement).

could care less about the site glass, would be nice but, meh.
Rebuilt the slave and master, huge difference !!
also, not using the aftermarket crap levers helps as well, they just have too much slop !!
next for me @ 111k is to rebuild the clutch over the winter with the rear master brake cyl, front brake cyl and front calipers
it would be nice to replace the brake lines as well ;-)

Good Luck

and i need to rebuild my right side carb, causing <2k rpm issues, only likes partial Choke

There used to be place in florida that sold stainless braided lines for gl1500. Replaced my rear line with one and wishing I had done them all.
