So my car is up in the air while I am changing the throwout bearing. I have had a ton of bad luck. One issue after another. So today while putting the starter back in, I had my hand on the right front wheel and went to pull myself out from under the car. It spun, but had some drag to it. Out of curiosity I spun the left and it is worse. I can hear the brake pads dragging bad. Any ideas, and is this normal for our cars? My car has 90,000 miles on it, and is very clean. There is no rust anywhere, and the calipers look like new. what should I check?
