I had a grinding noise also this week, but it was after I hit something in the road. My front passenger caliper was dragging, pretty much ate up my EBC pad.

 

Threxx, your problem is humidity/moisture combined with brake dust causing your grind. The vibration....well, probably warped rotors.

Dex, no problem, I understand the expectations of Lexus owners. The cars electrical systems have hundreds of thousands of parts in them. When ONE part goes bad it is a bad thing and the owners don't understand it. In my book, thats pretty damn good, but I do understand, if you would have to pay 3k for a part that failed just outside of warranty, it could be hard to swallow.

Just remember, they ARE cars.
