I have a 2008 GS SM5 with 33,500 miles, that had been basically error free, until now. A “Brake Failure” message has started to scroll across the display. There was nothing unusual that happened or done prior this. Brakes work fine, brake fluid levels good, and brake pads show about 60% to 70%. Tried the key off and out, overnight, and no change. Tried to key off, then on, then stepping down hard on the brake pedal, with no change. The closes “dealer” is about 5-6 hours away, one way! Trying avoid that trip. May have to. Any suggestions?
