Question about 1982 Yamaha XJ 650
1982 XJ 1100 Yamaha Maxim
the rear brakes are dragging and won't fully release until I crack the rear caliper bleeder, then its good for 3 or 4 hours of riding but the problem slowly returns.
I have fully bled and replaced the brake fluid, r & r the rear calipers and installed new seals (all looked in perfect condition, no scores, marks or corrosion)
I had an XJ 1100 and had the same problem. after paying someone else two diferent times I found an article talking about the very problem, (wish I could tell you where it is but) what it said was this system was prone to moisture getting in the rear master cylinder. I took the cylider apart and carfully cleaned all the brown residue out of all the small areas and orfices. then with a large suction/pressure pump bought at NAPA I forced good quality dot 4 fluid through the lines untill all the fluid came out clear (better buy 2 quarts this may take several flushings. then disasemble and clean the wheel cylinder as carefully as you did the master cylinder. This solved the problem on my 82 XJ 1100, the article said the trick was that if you live in a climate where weather chages with the seasons changing the fluid each riding season should prevent this from clogging again. Hope this helps, mine worked great afterwords.

Check the adjustment at the rear brake pedal. If you don't have any freeplay in the pedal, it's just going to keep pumping up.
