My wife's 2004 XC90 2.5T AWD is in need of new front rotors and pads. The car just got it's 60k mile service at the dealer and they said that the rotors were done and the pads were at 3mm. My question is which size rotor does my car have. At all of the online parts stores I have looked at there is a 316mm rotor and a 336mm rotor. I don't have the car with me so I can't check now, but I would like to get the parts ordered asap so I can change the brakes this weekend.

Also, does anyone have a recommendations on pads, besides the factory pads, I'm tired of all the dust, they are almost as bad as BMW factory pads?

What would be the cause of the difference in rotor size, AWD vs. FWD???

Thanks for your help...
