Went for the first ride of the spring yesterday. The 100 ran great until we couldn't avoid one of Pennsylvania's ubiquitous potholes. Front right took a shot and we immediately heard an intermittent metallic noise from the front right. Sounded like bearings to me (had plans to rebuild both front hubs this week) so headed for home, luckily only about 3 miles away. About 1 mile from home, the brake pedal became rock hard but I could still stop the car. When we get into the garage, all 4 brake drums were very hot and the wheels almost locked. After cooling off, the brake pedal softened and the car rolled easily. I am assuming that heat from whatever occurred in the front right caused this issue but any other thoughts on what to look for? Have not pulled any wheels yet.
