   The advantage of drilled and slotted rotors is that they allow the gas that   
   the pads generate to escape.  If the gas builds up between the pad and   
   rotor, the effect is a little like an air hockey table so friction is   
   reduced.  The disadvantage of slotted and drilled rotors is that they cost   
   more and are not easily resurfaced.   
      
   When you resurface rotors, you reduce their ability to dissipate heat so   
   they are more likely to warp.   
      
   Some things that can reduce brake fade and rotor warpage are selecting a   
   lower gear on long downhill grades, and if you have rear drum brakes, making   
   sure that they are adjusted properly.   
      
   I used to do a lot of driving in the mountains and did not experience brake   
   fade or rotor warpage on any of the Toyotas I had as company cars.   
      
   The only aftermarket brand you listed that I'm familiar with is Brembo.   
   They should be OK but before you go that route, try checking the back brakes   
   and shifting to a lower gear.
