Uh, the adjuster has been out of the lever like that since October? And you've been driving it? Good chance the lever is damaged. Should be a nice cup shape in the end of the lever. If it's been riding on that bolt out of position it's probably gouged up. Explains the tire wear too. That thing has to ride like crap like that, it's riding on the bumpstop on the right side, and probably bottoms out on the left all the time too. Sheesh.
