Why is there more brake dust in the rear brakes than the front?

Is this normal?

I have much more in the front than rear. I'm guessing that it's because the front's work harder due to shift in momentum.

normally it's the other way around.

It's nothing to be concerned about.

Do you have different brands of pad in front and back?

Brake ratio?

Well if the rear is drums then I would say that because the drums will hold in the dust since the rotors stick out in the open.

If the rears are rotors then I would say that it is due to the fact the dust on the front is blown away because it is the front of the car that gets most of the wind where as the rear of that car may not see much air going past it becuase of that cars piticular aerodynamics???

And yes typicaly it is the other way around but it may be that cars aerodynamics that make this happen on this model.

Just a guess but I suspect it's because the front wheel change angle allowing the dust to get blown out while the rears stay in a fixed position.

Should be the other way around.

Screwed up proportioning valve?

Low mileage.. Hmm... What does the dealer say?

My wifes 04 Volvo S40 is the same - i believe the mazda3 and volvo are based on the same design too. Maybe the pads are much harder on the front *shrug* i dont find the brakes poor by any means when im driving it.

If it bugs ya that much, go get yourself some better brake pads. I have good luck out of Wagner Thermoquiets.. They're worth the extra 20 bucks to me.
