I have a Honda accord 2008 which has performed well until recently. On my may to work I noticed my car wasn't accelerating as usual; it had this feel like it was dragging. On parking, I noticed smoke on my left rear tire. However, i thought nothing of this.
Going home in the evening while on the freeway, my car started decelerating and the brake pedal became very hard. Pulling to the side of the road, I shut restarted the engine but i could not move the car so I loosened the calipers and got some normal movement.
Any ideas on what might have gone wrong?
