Is there a way to turn off these sensors and clear the this red E-brake light? Or if it's easier, can I just clear the red E-brake light in INPA without doing any coding?
No. You need a new sensor. It is a part that wears out much like the pads. It has two wires embedded at an angle in a composite material of some kind. I don't know if it measures capacitance or what, but as the nub wears down, the wire ends get further apart (because of the angle). At a certain point, the ECU triggers the wear indicator. It won't go away until you replace the sensor. It is a $10-15 part and can be replaced without removing the brakes.
