#131 of 175 2003 Toyota Avalon
Nov 07, 2007 (8:14 pm)
I'd written before about my Avalon concerning the brakes and being told I had disk problems after recently getting new brakes, tires, etc. I was in Springfield, Va & took my car to the Toyota Dealer. He said there was nothing wrong with my brakes. There was still plenty of space on my disks. He said, there was no point in getting a brake job done or replacing the disks. You might as well keep driving it until they wear down.
The car shimmys when I put on the brakes. I have 4 new tires. Will this not wear my tires out very quickly?

That's warped rotors. Sure that might result in some irregular tire wear over a long period of time. Probably nothing you'd notice unless this condition went on and on for an intolerable period.
#133 of 175 2006 Avalon brake pads need replacement
Jan 06, 2008 (9:13 am)
I purchased my 2006 Avalon new and I have been the only driver. At approximately 24,000 miles I was told by the dealer that the pads were half worn; both front and rear. At 27,798 miles the dealer informed me that they needed to be replaced. I am the only driver of the car, I do mostly highway driving and I don't do any towing. It seems to me that this repair work for nearly $500.00 should not be necessary with such little mileage. In addition to this, the dealer informed me that my two rear tires are bald and they need to be replaced.
I called Toyota customer service and was told that although I have an extended warrant, brakes are wear and tear items and are not covered. The agent could not care less about the fact that the mileage was only 27,798. She suggested that I take it to another Toyota dealer for a second opinion. Regarding the tires, she suggested that I contact Michelin, the manufacturer. She staterd this was "not a Toyota problem to resolve".
Has anyone had this problem with the brakes and or tires? What might be the cause of this and what recourse should I take. My other car is a 2000 Avalon and I never had these difficulties. I was the sole driver of that car until I got the 2006 model.
Any help would be greatly appreciated.

There seems to be questionable issues with your dealer. If the pads were half worn-out at 24K, how did they completely wear out in 3K? Tire issues do go back to the tire manufacturer, but "bald" rear tires only on a front wheel drive car certainly doesn't seem normal.
I would find a reputable independent shop (maybe a Michelin dealer) for a second opinion, since brake pads and tires are not covered under Toyota warranty anyway.

With suburban driving the brakes could be half gone (front) and the rear should be almost new. As above, how did 3k miles finish off the pads? Not likely. My experience, anyway.
If the tires were rotated properly how do two go bald and two not? They should all be pretty close. Take the car to a Michelin dealer and ask the question...
This whole thing sounds strange. Like the dealer wants some money you don't need to spend. Good luck, keep the forum posted .

I have a similar problem. Please read my post My 2006 Avalon need new brakes.
#137 of 175 ABS Failure -- Pedal to Floor
Mar 02, 2009 (1:05 pm)
This morning I had a bizarre situation with my 2007 Toyota Avalon. My community received 1-2 inches of a dry snow overnight. I left my home prior to a snow plow showing up and needed to travel down several small hills to leave the development.
To say the least, the road was slick. So I kept my speed to about 5-10 MPH. On four separate occassions while traveling this 3/4 mile stretch, my ABS system failed on me. On each occasion, the ABS kicked in and was pumping like mad. After pumping for what was probably several long seconds, the brake pedal would sink to the floor. During these events, my car did not feel as if it was decelerating at all. And of course, once the brakes hit the floor, I had absolutely no braking ability.
Please note that I was not manually pumping the brake, but letting the ABS system do its job. In addition, I don't believe I lost the ability to steer the car, although steering was incredibly tough since the roads were so slick.
I was finally able to get down the various hills by mainly hitting up against curbs (and fortunately missing mailboxes and telephone poles along the way). Once I got to the main road (which was plowed), my brakes appeared to work fine. So I continued to work since trying to head back to my house up those snow covered hills didn't appear to be a good option.
The local Toyato dealer was kind enough to get me an appointment within the hour of my call to them. However, they were unable to find anything wrong with the brake system. They tried to simulate the ABS failure in a snow covered parking lot (which was several hours after my event...and thus the snow was at least starting to melt and turn into slop). Of course, they couldn't recreate the failure, but instead confirmed that the ABS system was working as intended. They also ran diagnostics, which showed that no ABS failure code was recorded in the system. Lastly, they called Toyota corporate who claims that no one else had reported a similar situation.
Of course, my car was out of alignment due to my curb riding. So I left with a $85 bill for an alignment along with the "call us if it happens again". I asked the service manager if he knew what he was asking me to do -- wait until the brakes fail again and hope that I'm still around to talk to them about it.
To say the least, I probably won't ever buy another Toyota. Not sure how long I'm going to hang on to this one either...which I also use to transport my family in. So much for their safety rating in my book.
I appreciate all advice, tips and suggestions!

The ABS' brake pressure sustaining pumpmotor is just a 12 volt DC fractional HP motor very much like your windshield wiper drive motor. This is the very same motor also used for TCS, VSC, EBD, and BA functionality.
If you read the owners manual carefully you will find that these other functions have a time out delay to prevent overheating of this pumpmotor. What the manufacturers do not seem to be willing to say, admit, is the ABS functionality has this very same limitation, if the pumpmotor begins to overheat then you will lose ABS capability .
If you happened to start out the morning with anything less than an absolutely FULL battery charge then even the WORSE. I would also clean and burnish the battery posts/terminals/connections as just a bit if additional insurance.

If you didn't lose hydraulic fluid I can't really understand how this could happen. I could understand a loss of vacuum to the power brake, giving you a very HARD pedal that might feel like loss of brakes.

When ABS activates to prevent wheel lockup/skid it releases brake pressure fluid back into the reservoir at/from the individual brake calipers. If the ABS pumpmotor cannot keep up with the rate of brake fluid pressure depletion due to ABS then the pedal will go (slowly...??) to the floor since the "makeup" fluid pressure must now come from the master cylinder.
That could be the result of a low battery, poor battery positive and/or negative connections, poor connections to the ABS pumpmotor, or a "tired" ABS pumpmotor. Most modern day vehicles have a time-out system to prevent the prolonged use of the ABS pumpmotor in support of other, ancillary, functions such as TC, VSC, EBD, and BA. Basically "reserving" some portion of the ABS pumpmotor for its primary purpose/use.
If some of these ancillary functions were highly active just prior to the need for ABS it is entirely possible that ABS capability would be foreshortened accordingly. And given the conditions stated it seems highly probable that TC would have been in use and maybe even VSC.
The ABS pumpmotor very likely has a permanent magnet rotor and it doesn't take many overheating cycles to compromise the magnetic aspects of the rotor. Therefore a weakened pumpmotor functionality.
