Yes, in general, the front brakes wear out much quicker than the rears because when you have heavy braking, you have what is commonly known as "weight" transfer to the front brakes. The best way of illustrating this is to think of a trick motorcyclist who slams on his brakes and makes the rear wheel come off the ground while braking. This is an exaggerated circumstance, but you can draw the analogy from this that under normal heavy braking, the rear of the car tends to lift, reducing the amount of weight on the rear (and thus the amount of braking).
