In the high humidity or rain the rear brakes lock. It makes a scraping and scratching noise, when the brakes dry out. There is no forewarning; noticed this problem since purchasing the vehicle on September 1, 2002. Have contacted three dealers, and a manufacturer's representative said that this was normal. One dealer did replaced the brake lines.
