In the 90's my almost daily driver was a Thunderbird SC with a 5 speed and 4 wheel disc brakes and my secondary driver was a '95 Ram 1500 with 4wd and disc/drum brakes.
I got 135,000 miles out of a set of front brakes on the Tbird, and the pads still had a little bit of life left in them when I replaced them. With the truck, the front brakes on the Ram used to be shot about every 10,000 miles. Same driver, drastically different brake pad life.
I drove the car 4 or 5 days a week. Semi highway type driving mainly. It was garage kept. The truck I drove 1-3 days a week, same semi highway type driving plus some local errands, it was parked outside.
When the weather was bad, storming, snowy etc I would drive the truck.
Pretty dramatic difference, but my experience shows how much brake pad life can vary.
