I asked this question a short while ago (in another brake thread) but got no answer...so I'll ask it again.
I had some work done on the Box a few weeks ago and the guy let me know the back brakes (esp outside pad, passenger-side) were near ready for replacing. I had just that wheel off a few days later and measured that pad: it's at about 4 mm, so I guess he's right. My front pads are in better shape: they have maybe 40% left.
If I just do the rears for now, is it bad to switch away from OEM pads for just the rears and leave the OEMs on front?? (If I switch, I would of course plan on switching the fronts to the same type pad when the time comes.)
