You may want to pull the ABS fuse and do a test run. If nothing else, this will at least eliminate the ABS as a possible cause.

Easier said than done. Has anyone tried to pull the ABS fuse? I tried and can't get it off, I even tried a pair of plier. thanks Lexus.:chairshot:

There should be 2 ABS circuit breakers in the engine compartment fuse box. I know others had the ABS sensor ring fail, which is part of the axle, and pulled the circuit breakers rather than have the whole axle replaced. Of course, now they don't have ABS, but it is better than it activating all the time. I am not sure if there is a trick to pulling the breakers and I can't check right now because the wife is out with the car.
I just want to update everyone. Finally, after exhausting other possibilities, I pulled one of the ABS relays because I couldn't get the fuse off. It is amazing how much faster the car stops now, however, the ABS light in the dash is on. So after $300 and countless hours taking the brakes apart / putting them back to together, I replaced 4 rotors, 4 brake pads, and 2 front calipers just to find out it is the ABS system that's giving the problem. Good thing is that I worked on the car myself, but I think everyone should try the easiest thing to do first when troubleshooting.
Now does anyone have any ideas which part of the ABS is at fault? Is it really the sensor ring? I had more faint in Lexus before owning one, now it has turned out to be less reliable than my Nissan Maxima with more miles. After 1 year of ownership, I have had to replace the alternator and now ABS parts. The transmission is holding up so far, fingers cross.
Hey rlin78
I've just read your post about your brake problem. I just bought a 2000 Rx 300 with 63,000 miles and I am having the exact same problem that you had.
I would like to know if you had the problem fixed and what part of the ABS was at fault and a ball park figure of the cost.
Thanks
