So I take my car for a drive and i smell the clutch slip/brake smell. ruh-roh. I pull over, and my pass rear tire is HOT. So i pull the wheel off, and i get the caliper off, and the shim is destroyed. remove the caliper, grease the pins, adjust the hex nut so that the brakes are adjusted properly, and button everything up. I get into the car, and the ebrake is loose, so i adjust it so that it grabs at like 10 clicks. I go for a drive, it's all good. Then on another drive, same smell so I'm assuming same problem. What do you guys think is going on?
