So, my plan was to restore my 1988 R100 RT after purchasing my GS. However, I spent a bit too much on my GS and now I have to put off the restoration. The bike really should have some repairs to make it more reliable so I can ride it until I can get to the restoration. I have some questions regarding the brake system.
The bike is ±35 years old. What are people’s thoughts regarding rebuilding the calipers and/or master cylinder? My thought is to disassemble and replace all the O-rings and gaskets at a minimum, and anything else that may seem out of spec. After ±35 years, I would think the O rings and perhaps the gaskets at the end or nearing the end of their economic/useful lives. However, I’m unaware of any major issues—the brakes seem to work OK at the moment. Should I be proactive here and rebuild them, or wait and repair as needed down the road? FYI, I do plan on replacing the brake lines with braided stainless lines.
