Can you use wd40 on disc brakes?

Why are my brand new brakes squeaking?

One of the most common reasons that new brakes squeal is that there’s moisture on the rotors. When they get wet, a thin layer of rust will develop on the surface. When the pads come into contact with the rotors, these particles get embedded into them, creating a squealing sound.
