Once the sensor is tripped, it has to be replaced.
Or you can cut the wires, tie them together and be done.
Oddly when I changed my oil in July, the brakes icon came on when I did reset the CBS for oil - it was not for brakes oil and I couldn't reset the new "mileage to go". I found that there was some undetermined kind of interference. But when I "took care" of the front sensor, the message just went.
I have 3/16" of pads life at 60000 miles. They are easily good for another 10000 miles although I hate the way they immediately get dirty. Rears pads were changed at 40000 miles. I do heavy traffic almost every day. These brakes are awesome.
