Finally
After about two sprays a day for better then a week, and a few whacks with a hammer I finally got the brake master cylinder disconnected from the brake line. Now the problem is that I can’t get the reservoir cap off. Fortunately I started spraying it with “liquid wrench” a few days ago. I also need to find someone to do a master cylinder re-manufacture. So I’m a battery and a petcock away from trying to start the Glide and a complete brake system away from stopping.
