EBD is the electronic braking standard on the mk4 and up cars in the US. It's connected to the ABS and brake system, basically it brakes the rears more than the front during light braking. The more you brake, the more it biases braking action towards the front. This is why the rears can wear out first.
Also note that the brake pads and rotors are designed to wear out at about the same time, so rotor replacement is suggested. I haven't tried every possible brake rotor out there, I suggest buying quality parts and staying away from drilled rotors because they can crack.
