Working on a 1998 V-70 xc.

When I took our old Volvo to the our good indy euro vehicle specialist, they generally replaced the rotors each time they replaced the pads. The car I'm working on now has old rotors and new pads in front, and needs pads in rear. Rotors all around are not too bad, just wondering what common practice is on these.

They do seem to wear down more quickly than the rotors on heavier vehicles I normally work on, perhaps it is the composition of the steel, or more likely, that of the more modern brake pads.

 

two reasons to replace rotors - grooves from prior worn pad or the rotor is approaching the serviceable thickness limit (mm stamped into the edge of the rotor). If your surface is flat and the rotor is within tolerance then you can reuse, but as noted its easier to replace than resurface
