   There is no rule of thumb for brake wear because it depends more on the   
   driver, vehicle location and the pad materials than anything else.   
      
   Drive out in the plains where the only hills are long and low and the   
   brake wear is going to be much different than if you live in the   
   rockies. Same with driving in New York City versus San Fransisco.   
      
   Another factor is the vehicle itself and how it is set up. Some will   
   chew through brakes fast while others barely nibble. Some will go   
   through brakes in 40K or less while others might make it to the junkyard   
   on the OEM rears pads.   
      
      
   The Journey we have  had all the brakes done by the dealer with OEM   
   parts prior to our purchase, They have about 55K on them and the fronts   
   are worn maybe 1/2 way. The rears however were just replaced, but not   
   for wear, the rotors rusted into junk and damaged the pads. So it got   
   new NAPA coated rotors and premium ceramics to see how they work on it,   
   have had very good service from them on many other vehicles.
