This was a problem I had on my 81. It uses a single piston caliper. Mine was the master cylinder had gotten contaminated. It plugged the holes up in it so brake force was reduced. $35.00 kit on eBay and some serious cleaning fixes the problem

Hello I'm a new member I have used this site time to time to gain knowledge on where to get parts for my girl (GL1100I) as we all know parts are getting scares and it's nice to have other people who have the same thing in common. I look forward to people picking my brain as well as I picking theirs.
