As others have mentioned, braking system life is such a variable thing.
Yes driving habits can make huge a huge difference to brake life....many of the modern vehicles go and stop so damn
well people never have to learn to conserve brakes or leave extra margin in daily driving.
Lots of people, particularly women ( sorry its just the way it is) drive their modern fairly heavy vehicles pretty hard, but don't realise untill the brake and clutch repair bill comes in or they realise how much fuel they are using.
Then there is the huge variability in brake system design.
Some of the manufacturers can design braking systems that are efficient and
well balanced and designed
well from end to end.
Others frankly are just thrown together..then they have to use crude engineering tricks to make the brake system tolerable.
Methods such as
Applying excessive amounts of brake boost, to make the brakes seem more efficient.
Relying on the ABS to cover up for failures in fundamental design.
Use of agressive pad materials and soft metals in disks and drums to incresase braking efficiency where better design would have resulted in longer brake life.
I've always scratched my head and wondered why there has always been such a good market for replecement brake rotors in very late model vehicles.
There are all sorts of garrage tales about what causes a brake system to have such a short life.
The larger the braking surface especially the larger the diameter should result in better efficiency and longer brake life.
Hard pad materials should not result in undue rotor wear, the opposite in fact.
If a particular vehice has a tendancy short pad and rotor life, that is entirely due to bad design on the part of the manufacturer.
Of course brake surface contamination ( such as dust, sand, mud and water) can wreck brakes in very short order.
