Wearing pads rather than discs?

[Coupusmaximus]

Hey there, I just picked up my BF GT after its 45,000 km service, apparently I have about 5,000 km's before having to replace pads and rotors (standard Brembo set up) at a cost of $2200.00. I thought I would need to change pads a few times (which I haven't) before having to replace rotors, I was told the pads and rotors wear at the same rate, is there a softer pad I can run, to delay having to replacing my rotors? Thanks for your time, cheers, Lee.
