2004 Olds Bravada needs new front brake rotors every year

What is your question?

I have a 2004 Bravada AWD driven less than 10000 miles per year, and had to replace front rotors in Feb. 2009, again in Feb. 2010, and now need to replace them again. Mechanic says it is caused by the equalizer and that the problem is common. Has GM had recalls or service bulletins about this? It has to be a design flaw.
