While driving (secondary roads, suburbs) noticed 'spongy' brake feel and strange sound from left rear. When I got home (after about 15 min of driving), left rear disc was glowing orange/yellow and smoke was coming from the wheel. Had rear pads replaced/reset. Problem returned 2 weeks later. After a short drive, noticed smell and saw smoke coming from left rear wheel. Lifted car and left rear wheel would not turn. All other wheels are fine.
