I was driving 2004 Toyota Sienna xle awd, 109,000, with bridgestone rft snow tires. At 15-20 mph on dry pavement, I tried to stop quickly for a dog strolling in front of us. The van slightly slowed, the dog waddled out of the way and we came to a rolling, gradual stop with the brake pedal depressed fully to the floor. I hadn't time to pump brakes and I don't know if it would have mattered. The Toyota dealer couldn't duplicate problem and said pads, etc; were good. Has happened to me this one time only, but google search suggests others may have had this experience. Thanks.
2004 Sienna, had to replace brake pads twice. Brought vehicle in for 30,000 mile check, and was told that they were again 75% worn out and need to be replaced for the third time. Also, had to replace all four tires at 18,000 miles.
Upon having the 15,000 mile maintenance done I was informed that my brake disc pads needed to replaced as they were down to 20%.
The brakes pads on my 2004 Sienna had to be replaced at 15,000 miles. Was told by the service advisor he has seen Siennas coming in at 10,000 miles for brake jobs. A Toyota technician told me the reason for this was because Toyota was using softer pads so the brakes can be quiterer. This is a very expensive job for something that should last into the 30,000 mi. Range. This is very dissapointing coming from Toyota.
Brake degradation on 2004 Toyota Sienna. Toyota Sienna brakes began to severly deteriorate at 14,000 miles. Pads worn beyond safe use and rotors glazed and warped.
I am having the brakes on my new Toyota Sienna replaced and the rotors resurfaced at 24,000 miles this seems quite early to me. The consequence is the price to do this is $195 or I could get the new "type" of brake pad but that cost $235 (they also didn't have it in stock). I have read other complaints of persons getting their done as early as 10,000 miles. This is not right!.
