I bought my Oldsmobile Silhouette in 2000 and had no problems until about 30,000 miles. The driver's side front rotor was scored because the brake pad was worn unevenly. Took it to my dealer and was told I was driving incorrectly. The right front was fine, only the left was worn. So I had the left rotor, pads, and caliper replaced. At about 55,000 miles it did it again. Took it to three dealers and they told me the same thing. I wish I knew what I was doing wrong! (LOL) After talking to several GM mechanics, I found this is not an unusual problem with this van. Everything else works fine-but every 25,000 miles I had to replace the brake pads-I can't afford a new rotor each time.
