Why don't my brakes last on my 1999 suburban
A lot of things can affect brake wear, composition of the lining is one of them, if the lining is too soft then it wears rather quickly, too hard and they wear on the brake drums or rotors, then there are mechanical issues, are the calipers sticking, do they slide on the mount as they should, are the hoses good, etc. Adding a load can increase wear, driving off road also causes wear from fine dirt. I liked using semi-metallic pads and shoes in my shop, for most everyday driving they perform rather well, beaver duty calls for better quality like full metallic or ceramic linings. So not knowing what kind of stuff you do with your rig, but it sounds like you need better quality brakes.
Where and the manner in which is driven will affect how long the brakes last. Are you the only driver?
