The brakes on my '03 didn't squeak, but definately lost their grab before 20K (has 31K on it now). After a hard stop it would regain it's ability to grab without having to push too hard on the stop peddle, but that grab wouldn't last long. Having just picked up the new '4. 5, I realized just how much braking the '03 lost. In recent years I've had to replace many pads & shoes that had lots of material left on them, but had become to hardened to be useful...
