I have a 2007 xc70 with 22,500 miles and the front brakes already need replacement, they are down to 3 mm already. Is this normal for this car, I get on average 38,000 miles on my 2000 s70. My wife does most of the driving at an average speed of 21 MPH, so mostly city, but I know she is not to hard on the brakes. It seams this is to soon to change brake pads. I will try diferent pads.
