After a short drive I smelled brake dust, and my left rear wheel was warm. I pulled the wheel and had to use a "c" clamp to push caliper piston in a little to be able to remove caliper. Disc pads still had a lot of pad, and the rotor is not grooved or apparently damaged (unless it's warped). I did use the emergency brake on the short trip. Could the e. Brake somehow be dragging on one side? The VX has 87k miles, and the rear brakes were replaced once already. Has anyone had this happen? I did notice that the piston in the caliper seemed stuck. Also, my ABS light has been on for about the last 10k miles. Could this be a factor? Any help/ advice will be appreciated. Thanks.
