I own a 2002 Toyota Sienna and there is a problem with the rear brake rotor drum and pad. Frequest squealing and premature pad wear is evident since 5,000 miles. The dealer told us Toyota recognizes the problem and will investigate a solution. They originally stated they expected a reply by Toyota by July/August 2002. We still do not have any information that leads us to believe this issue will be resoplved anytime soon.
