On the third drive of my day, i noticed my car would start to jerk back and forth like a bucking bull with acceleration, and then while coasting and even braking. Noticed my drivers side wheel area had smoke coming out and a burning smell. Attempted to fix for stuck calliper, but the piston pushed in like butter. Did a spin test and the hub would just get locked, only on the drivers side, even after releasing the brakes. It would eventually let go. I replaced the caliper anyways, and pads and rotors. Also had a leak from a line connecting the cylinder to the abs module (just had this replaced last year). It was a huge leak, so we tightened the line in and no more leak. No codes showed up.
I know it’s not the best description, but any suggestions would be great.
