I normally used to use the cheapest I could get my hands on, since I figured that they were going to wear out anyway. However that was before I drove a 'burban. Never drove anything so heavy. This time around I went with Carbon/metalic, and noticed the stopping power is much better. The only suggest that if it's been over 60,000 miles since the brake fluid was changed you might consider flushing the system at the same time as changing your brakes. It's a sucky job, but in the end it's worth it.
