From what I understand it is not at all uncommon for those that track their cars to pull the sensor out of the pad and zip tie it to the frame. Apparently they tend to melt under the heat of track braking.

I replaced mine last month and it appears the business end of the sensor is simply an insulated wire loop. As the pad wears away the wire is exposed and friction from the rotor wears off the insulation causing metal to metal contact with the rotor. Soooooooo, I would think if you eliminate the contact, you eliminate the dash light.

Not sure if you could simply unplug the whole sensor without getting a CEL or some type of other light.

My 2 cents
