There is no rule of thumb for brake wear because it depends more on the
driver, vehicle location and the pad materials than anything else.

Drive out in the plains where the only hills are long and low and the
brake wear is going to be much different than if you live in the
rockies. Same with driving in New York City versus San Fransisco.

Another factor is the vehicle itself and how it is set up. Some will
chew through brakes fast while others barely nibble. Some will go
through brakes in 40K or less while others might make it to the junkyard
on the OEM rears pads.


The Journey we have had all the brakes done by the dealer with OEM
parts prior to our purchase, They have about 55K on them and the fronts
are worn maybe 1/2 way. The rears however were just replaced, but not
for wear, the rotors rusted into junk and damaged the pads. So it got
new NAPA coated rotors and premium ceramics to see how they work on it,
have had very good service from them on many other vehicles.
