How many miles' usage would you expect to get out of a set of disc brakes? Roughly.
I know it depends on a lot of different factors such as how heavily you brake and whether you do a lot of nose-to-tail start-stop driving in town or mainly drive on motorways/freeways.
I ask because my Peugeot 306 seems to go through brakes at a great rate - every other service (so every 24,000 miles) I need new pads (especially at the back) and/or new discs where the pads have worn down far enough to score the discs. This is a small car about the size of a Ford Focus or a VW Golf with disc brakes all round. I would have thought that my brakes might last longer than average because as an Advanced Driver (member of Institute of Advanced Motorists in UK) I tend to look further ahead on the road and slow down by lifting off the power if possible rather than braking for every bend, and I brake progressively: light braking at high speed, getting heavier as I slow down.
Is 24,000 miles on a set of brake pads/discs fairly typical or is it excessive. And why would the rear brakes wear out more often than the front brakes, given that you'd expect the front brakes to bear more of the braking force?
