I'm trying to get my emergency brake working so I can take it in to get it inspected. I seems so somewhat work, just doesn't lock the drums in the back. I pull up on the handle and it is tight as can be. I tried tightning the adjustor, just make the handle tighter. The arms seem to push the pads out, they tighted up when I pull the brake, and the rear brakes do work normally. Anybody have any suggestions on this?
