Drilled and slotted rotor pads installed. Smooth braking, but no better than the original. The effort on the pedals is about the same. Update: It seems that the pedal effort has now decreased slightly. There may be a small but noticeable improvement in wet conditions - it hasn't rained in a while so I can't comment on that yet. Not sure about the lifespan of the pads but they are carbon ceramic. They've had a bad life with ceramic seals in the past.
