[Oh Haha]

I'll take a stab at this:

What model Caddy? How does he drive? I have had several GM cars go through rotors in less than 25,000 miles. Not all mine but owned by friends and family members. I was told by a local GM wrench that some are just not up to the taskof stopping a big car and wear out faster. That said, ,my last Vibe only went 30,000 on the original rotors and pads. Although it was my workmobile I didn't drive it hard or abuse it. My Mom's Hyundai needed brakes after only about 25,000 miles.
