Gary if you have had 60,000 km out of the original pads and rotors then your car must have been driven very sparingly. I think that's a great life and if you get another 15 k you should be a happy camper.As a side thought, I never realised the difference between new/replacement time was so small so as I am 0.5mm away, that would equate to a quarter life left on them - which in my kms terms would be about 15,000kms - or another 18 months of motoring!!
Not sure what to do now especially as the braking is showing no signs of wear etc
