If you really want to do this, and "humidity" is the theory, then you need to drill two different size holes. You see, humidity is water. water is a molecular structure of oxygen, hydrogen, oxygen . oxygen atoms are a different size than hydrogen atoms, so you need to drill different size holes when the molecules split into the seperate atoms from the heat build-up from the friction caused by the brake pads being squeezed against the rotors. I recommend a one inch hole for the oxygen atoms, and a 1.5 inch hole for hydrogen.
