2005 Toyota Sienna LE.
Replaced original brakes at 45,000 miles due to wear and pulsation/vibration when braking. Work done at Car-X, all 4 rotors turned, new semi metallic pads all around.
10,000 miles later, vibration/ pulsation back. Took back to Car-X and they wanted to replace all my rotors to honor their warranty on the pads. Took to an independent mechanic. He said it looked like my rotors had never been turned and were now warped. He replaced front rotors and pads with Raybestos rotors and semi-metallic pads (the best I could get for it - U.S. made). He said the rears were warped a little also, but were OK, since the fronts do most of the braking.
10,000 miles later, and the vibration/ pulsation is back. I took it back to him and he said the rotors and pads on the front were burnt up and the rotors were warped again. He said Raybestos wouldn't honor the warranty since the rotors were burnt up and they said it was due to abuse! He says it looks like my wife rides the brake, but I know she doesn't. Besides, how did she get 45K on the OEM set, then only 10K each on two replacement sets?
Something else is wrong with the brake system, not just the way the van is driven! In the mean time, I've spent ~ $800 on three brake jobs in the last 18 months!
Just to add to the comments, I have owned from new a Sienna 2004. I have put in 4 sets of brake pads + original (all original from Toyota), and it now looks like I need a 5th set. I am getting around 15K per set. Something is differently wrong with the wear on the Sienna. I now have to replace the rotors.
I have solved the problem. If you have drums, upgrade the wheel cylinder with a 2000 4runner. There is a slight mod that needs to be done. The housing and the bolts are the same. The part that contacts the shoe is bigger and longer, so the tips of the shoe needs to be cut back some so the cylinder will fit. The factory wheel cylinder size is 7/8, the bigger one is 15/16. The van now brakes more evenly. Hope this helps. If you have any questions, email me at firstname.lastname@example.org.
I own a 2001 Sienna. I am sitting in a store for the first time to replace the pads and rotors. The mileage is 130k!
There are definitely some problems with the later year models!
I own 2007 Sienna LE, and I changed the front brakes myself after 92 000 miles. I purchased after market ceramic pads at price of $100.00 a set, and it took me about half an hour per wheel. Don't be afraid, it's a very simple job.
Replacing disc brake pads is so easy I can't imagine paying a shop to do it. My wife can change a set of brake pads on two wheels in half an hour.
My 2003 Sienna does not eat brakes, period. I just finished replacing rotors and pads for the second time at 148,000 miles.
It is the driver who overuses the brake that causes the fast wearing. Treat the brake pedal as the thing that increases gas consumption and causes early brake failure. Every time you brake, you are wasting momentum. It takes discipline to do this, but it can be done. I learned how to stay off of it, and I get 27 highway and 21 in town. Inflate the tires to 42#, max 44#.
My last car was a 98 4Runner, and I finally did a brake job at 120,000 miles.
