There is to much play in the right brake lever so I tried adjusting the front brakes through the window, but couldn't get the adjuster to move. Removed the brake drum so I could see more clearly. At most the adjuster would only move a 1/4 of a turn which didn't appear to be enough adjustment. The lining is within the acceptable thickness. I'm not sure if the adjuster is faulty or if there is something else I am missing. Any ideas?
