1) It will rid the pads and rotor of superficial oil, grime and contaminants that inhibit friction.
2) It will reshape the pads so that they conform more accurately to the rotors. After breaking in more of the pads will contact more of the rotor.
3) It will increase stickiness (coefficient of friction) of the system by transferring a thin, even layer of brake pad compound to the rotor. Read more of this post
