2001 Eldorado ETC
In Feb I bought my 01 ETC with under 15000 original miles on it. As I drove off with it to bring it home the first time I used the brakes I could feel vibration through the pedal. At higher speeds it was really bad causing the car to shudder. Bad news was I had a 1700 mile drive home ahead of me, 3 days to get home and it was pouring rain out. I quickly checked to make sure a wheel wasn't loose or something. I decided to head home and tried to baby the brakes any time I had to stop. Long story short, by the time I got home they were great, smooth as glass with no noticeable high spot at all. My theory is that the car must have sat for a long time and got some corrosion or rust on the rotors that eventually came off with use. Once home I had the wheels off and the rotors look fine and there's lots of pad.
