also driving habits, if your the kind of person that zooms up to a stop sign and then jams on the brakes you will eat them up a lot faster then someone who coasts down a lil before applying the brakes
I fully agree. the family truck, the old 73 Ford F350 Cab and chassis with a 12 ft flatbed, 390 4spd manual and 2wd that Grandpa bought new has like 150 or 160K on it and it has its original brakes, except for ONE pad (not a set/pair, just one) that was changed due to a seized slider pin at around 30K.
it has pulled a trailer often, been near 30K on the Idaho farm with bales, and been up near 20K hauling machinery from colorado to idaho and California and all between. 2nd gear pulling the rockies on I70 once.

that granny low has made up for the 390 a few times. original short block, but it has been sitting awaiting its 5th set of heads. ford for ya, good chassis, but the engine sucks.
anyhow, back on brakes, I guess I will need to do something sometime on dad's 3500HD, the rear discs have grooves in them, I assume from rocks wedging in and cutting a groove? still stops fine. did a run dragging crap back from an auction, figured up near 30K lbs with only the truck brakes, and it could lock them up on gravel, so I guess we are still good.
