I like Textar Yellow Box pads and Balo rotors (learned from this site).

Sometimes the lip on the rotor can eat into the sensor, even though you may have some pad left. On many cars you can look and seee if your rotor 'lip' is big through the wheel. Another indicator of this is if the light is on with no brake pedal. If it is worn pad on good rotor, then you can turn the light on and off with your foot. If the light is different, it is lipping involved, and maybe more.
