95 Suburban Brake Wear

ANything regarding the excessive brake wear on the front brakes of the 1500 2WD Suburbans? I have replaced the calipers, rotors and pads iover the last two years, and when examining the rear shoes, they show little wear. Seems as if the overall majority of brake use is occurring on the front end. I recall seeing a reference to a TSB regarding this issue, but cannot locate it now.
