Replacing piston and cup set on rear master

The rear MC rarely gives a problem on these bikes - very reliable design. The only time I've pulled them to bits is when they've been jammed after sitting for a long time.

I replaced mine when I first got the bike. I wanted peace of mind that my brakes were in good working order. I also rebuilt all the calipers and the front master cylinder. At minimum I would disassemble, clean everything and inspect the MC cylinder bores for pitting. As soon as I can scrape up the money I am going to replace the rubber lines with braided stainless lines.
Piston

Well, considering this post has been 'alive' for almost 24 hours, I'm assuming this is a part that seldom wears out.:-k

Just last night I disassembled the rear caliper & MC on my 850GLX. Although it was working, I figured it was pretty gunked up in there - I was right. The whole system was full of old brake fluid with the consistancy of vasoline. Amazing it was working at all.
I cleaned & inspected all the little piece parts & put it all back together with new pads; didn't replace a thing.
For the money involved ($0), and the time invested (2-3 hrs) it was worth it to me to know the rear brake system isn't going to suddenly fail due to neglect.

This is why I always do mine. This is a picture of the front caliper, I am the original owner and this bike it has always been garage kept. The OEM caliper kits (piston & both seals) are only $ 20 or so and most are still available. Cheap insurance IMHO. I have not heard much good about aftermarket kits.

Im about to start into reassembling the entire brake system on the GS1000G i just recently picked up... the PPO had torn them apart, and they appear to be in pretty good shape..i will go thru them however, and clean them out more. The pistons arent bad looking, a couple SMALL pits in one, you think that will cause major issue??
