I have a 2009 Honda Accord Coupe. I recently had to travel abroad so I left my car idle for about 3 months. Today when I started my car and drove around the block I realized that its making a weird noise like its dragging a metal behind it which has contact with the road or its like two metal rubbing against each other in a continuous spin. The break works fine but I am worried. It only makes the sound when I am breaking and I am not sure what to expect or if its ok to drive or not etc. Please advice. Thanks.
