Brake Foundation Components Problems of Toyota Sienna

I have a 2005 Toyota Sienna van that has intermittent brake failure. It normally occurs when the car is cold. I have run several red lights with the brake pedal pressed completely to the floor and my wife has driven through two yards. The brakes function normally on the first several applications but on the third or fourth application they will occasionally fail. My dealership has replaced the master cylinder and done "diagnostics" at least 8 different times but consistently find nothing. They did tell me that other vehicles were experiencing the same sorts of problem and it had something to do with a new valve timing on the 2005 model and the vacuum was insufficient until the car was warm and that I should idle for 5 minutes before driving. This seems to work more consistently but I still have episodes of poor braking. We have been attempting to have this resolved for almost 18 months.

Brakes squealing at low speeds. I have repeatedly taken the vehicle in for this issue to be told it is not a safety issue - ergo, they cannot fix it.

Brakes squeak when applied at low speed. Dealer fixed it three times, but it is back again. The van was purchased new and is still under 3 year/36,000 miles warranty.

Vibration in rear brakes causing a harmonic noise when coming to a complete stop or if on a downward incline with brakes applied and just barely inching along. This is not the normal squeal from brake pads. I have been concerned that this vibration is causing other parts to become loose. I purchased the 2001 Toyota Sienna xle van new in sept 2000. All of my service is done according to Toyota's schedule and at Toyota of greensburg, PA. The noise started aprox. Feb of 2002 with 19,000 miles on the vehicle. It was reported to Toyota of greensburg, PA on may 10th of 2002 with 22,166 miles. Between may and August of 2002 the van was taken to the dealer 4 times for this problem. During that time they replaced the linings and drums, cleaned the brakes or did something other but the noise always comes back. On August 5th 2002 Toyota of greensburg told me that Toyota was aware of the problem and working on a fix because it is happening on all Sienna vans since 1998. Between then and April of 2003 I keep asking about the repair and the answer was it is not ready. At that point I went to Toyota's arbitration process but they would not do anything since the van now had over 36,000 miles even though the problem started well within the warranty period. I feel there is a vibration problem (sometimes you can actually see the road wheel vibrating also) that could cause other more serious problems but do not know what else to do. As far as I know Toyota has still not developed the repair.

At all times when applying brakes they would make a high pitch/grinding noise. Did not affect stopping. Took vehicle to dealer, and was informed that entire braking needed to be replaced. Consumer was also informed that replacement parts are defectively designed, consumer stated that the backing plate is too thin and defective. Left front rear wheel lug nut was cross threaded. Knocking noise from the right front when going over bumps, dealer replaced strut mounts.
