Hey all, been a while! But I'm back lol! With questions! So I was getting my 1980 XJ650 ready for spring riding, and I noticed that my front brake is stuck, the front wheel wouldn't roll at all. It did this same thing last fall, too. The brake caliper has been rebuilt, and my lines are braided stainless. I got all the parts from Len, a few years ago. I rebuilt the master cylinder last fall when the front brake stuck like this the first time, figuring that was the problem. Then we bled the brake lines again, made sure the brakes were working properly, and it's just been sitting over the winter since. Now it's stuck again. When I opened the master cylinder yesterday, I can tell there isn't any dirt or anything blocking the return, the brake fluid looks perfectly clear, with nothing floating in it. Any ideas how this happened, or what I should do? I did already take the caliper off so the bike will roll until I get this fixed, but that's it so far besides checking the inside of the master cylinder. Thanks ahead of time for any help!
