   Not quite.  The slots and cross drilling on the rotors allow the gases that   
   the pads generate when heated to escape more easily.  If the gas can't be   
   cleared from between the pad and rotor quickly enough, the effect is kind of   
   like an air hockey table, reducing the contact between the pad and rotor and   
   creating brake fade.  The slots in some pads serve the same purpose.
