I own a 2004 Toyota Sienna I bought new that has had to have the brake pads replaced 3 times in 62,000 miles. The last 2 sets only lasted 17,000, but the factory ones lasted 27,000. It' was worn out rotors, and had to replace those twice. It wa sbecoming very expensive, and seemed to be a product default. No other mini van I drove had anything like this.

2004 Toyota Sienna, left outside in long term parking for three weeks, during that time it rained a lot. Upon return and backing out of parking spot, a popping sound was heard. Since then every time the brake is depressed a thumping noise can be heard from the tire. Inspection of the tire didn't reveal anything stuck in them that would cause the noise. After bringing it to the dealer for servicing, the technician explained that rust build on the rotor actually fused to the brake pad thus causing the popping noise. The thumping noise when the brake is applied is caused by the brake pad rubbing against the rust on the rotor. Toyota motor Corp. Has refused and so has the dealer to replace the rotor since they say it is a wear and tear item and has exceeded the warranty period so I will have to come up with the money to replace them. There should not be that much rust on any part of an 04 Sienna that it would fuse to another part of the vehicle. This is a defect and should be handled by the manufacturer.
