Same here, had to replace my rear rotors under 30,000 miles!!!, they were real crap from Isuzu!

I realized there was a problem when I was traveling 60MPH down hill towards a light and before I knew it , it changed red and I slamed on the brakes but the truck didnt stop and I slid right through the intersection and red light. Lucky I didnt get hit. Thats when I brought it in for a brake job!

I didnt put on fancy replacements, maybe I should have. The braking/stopping power is much better but still not great.
