this weekend, i was working on getting the bottom calipher bolt off. i was putting all my strength and weight on it, but the thing just wouldnt budge. i ended up breaking two socket wrenches because of it, so i gave up, but my tire back on, and took it to a shop. turns out that the bolt had seized and their impact wrench had a lot of trouble getting it out. the guy told me that heat caused the thing to melt, and i was just wondering if anyone else has heard of this happening before and why it just happened to one bolt and not any other one on my car
