Like ALL things great and small. Break life depends upon two major factors.
If you do A LOT of stop and go city type drive. lESS miles.
IF you do a high percentage of miles on a freeway interstate not having to hit the brakes a dozen times a mile, more like zero with cruise on....you will get 2-3x the mileage of the city person.
I have best I can tell, 130k on my 1500. I go 160k on an 05 DW GM crew cab. Replaced the brake pads and calipers on my 92 Navistar a year ago with 170k miles. That rig does mostly non freeway miles.
Even my 1990's GMs, got 100k out of rear drums, 25-50k out of front pads, depending upon if an auto, lower, vs manual trans. Not to mention 30-40k per auto trans rebuild vs 80-100k miles per clutch....
Today's rigs are better ALL around than thru the 90's.
2000 on up, ALL brands started getting some serious improvements.
