I drive a 2003 Cadillac Cts. I noticed the brakes seemed to need repair (not responsive enough) and the "brake light" came on. My car had approx 70000 miles and the brake lines had corroded! I have the brake lines that were removed. A car with 70k miles should not have corroded brakelines. In addition, it took almost 2 weeks to get replacement parts and cost $250 to repair + rental car. This was a really bad accident waiting to happen.
