When it's time to replace brake pads, inferior aftermarket units will just not do the trick. They often fail prematurely or don't give good brake performance. Apart from that, most will leave your wheels covered in dust.

If it's time to replace your pads, then you should also replace your rotors to get maximum braking performance. With a new pad and rotor set on your vehicle, stopping will be completely restored. Enjoy the stopping you liked when you first obtained your vehicle.
