1995 Avalon, 100k, everything works on the car but the brakes will stop the car after about 10 to 15 minutes of driving all by themselves. By this I mean, you will be on the freeway just driving along and the car will just stop, the front brakes will actually stop the car and lock up without applying the pedal. Once stopped, the car will not move. If you wait for about 10 to 15 minutes, you can then drive the car again but it still feels like the front brakes are applied a little. I am getting ready to replace the front rotors and pads as they are now warped from heat, but what if that is not the problem? It will just warp the new front rotors as well. Any suggestions?
Look through the fuses and relays.
Pull either the fuse or relay for the ABS system. See if that helps (as Clay said).
Other than that, driving with the brake pedal down?
I would suspect the brake booster more then the ABS remove the line from the booster (vacum) cap it off and road test see what happens becareful brake pedal will be very hard to depress.
Thanks all for your answers, I had also posted this question up in a Toyota forum and was told to check the brake lines. They said they can collapse with age and act like a one way valve. I am off to the parts store to pick up new pads and rotors, looks like I will be picking up new lines as well.
Audi 5000s do this a lot, and it's ALWAYS the master cylinder. Next time it happens, crack the brake lines at the master cylinder and see if the brakes release. Easy to do, could save you a buncha time and money. The Cap'n
Thanks Cap't, I picked up a new MC while I was out since I found a leak coming from the one that is on there. It is most likely the culprit so I figured I would cover that base while I was in there.
Thinking back on my post, it's kinda funny to be describing "unintended deceleration" in an Audi 5000 ...................... The Cap'n
