The battery died a few days a ago so the zed was sat for a day or two. put the battery back in thought everything was fine but ohhhh nooo. The back drivers brake seems to be stuck on or so i thought. if you either put the car in 1st or reverse the car wont budge, the other 3 wheels are fine and free. cracked the caliper off the sticking back wheel but the the pads aint sticking to the caliper which i thought was the problem. so with the caliper off you can only rock the disk back and forth about 1cm, somethings stuck and i dont hav a clue what it is, so if anyone can shine a light please let me know
