everyone with cheep metallic break pads has this problem, switch to ceramic and it will clear right up.

I guess I make the 2nd Tit. Gray in Maryland <g>
A week after I washed my MZ3, I noticed same build up. I don't have a solution though. Anyone know?

I'd expect more on the front, not the back.
This has been discussed several times under suspension/brakes read the bottom of this post, locked by Dinu1, and the 4 threads he refers a fellow member to. http://www.mazda3forums.com/viewtopic.php?t=2361

We are going to be offering some Porterfield R4-S brake pads for the Mazda3 here pretty soon. For those that dont know, the Porterfield R4-S pad offers higher friction levels for better braking, better heat/fade resistance, and MUCH less brake dust.
We ran a group buy for the Mazda6Club guys and will do the same for the Mazda3Forums. I am waiting to get a tracing of the stock Mazda3 brake pad and then Porterfield will be able to move forward with production. As soon as we have the parts, we will list them in our Performance Parts directory for the Mazda3.
For more info on the pads, go to:

I was thinking about the EBD problem too..
but i've never thought of the airflow problem... interesting to know
but anyway... when i see the brake dust build up... it was nice too cuz the dust changes the rim colour to look like gun-metal rims.. and on a titanium grey colour, they match pretty good!!

I'm not a 3 owner yet but looking into it. So i'm reading these
forums to get a feeling about problems ppl face with it.
Now about the excessive brake dust on the rear brakes compared
to the front ones: i've read on a report of a guy that did a test
drive that he observed that the car wasn't 'digging' as much
when braking hard, that is the car wasnt lowering its 'nose' under
a braking condition. Thats a good thing from a car dymanics point
of view since it keeps the car balanced etc. So, since the car's
braking system is controlled by the EBD system, *maybe* this
behavior is what Mazda engineers wanted. Maybe they make the
rear part brake more than the front to equal the inevitable
distortion of the car's balance during a brake. Just an opinion...

since many new cars like camry/accord etc whcih have this EBD function, wont let the car's nose dive when braking hard... I also notice this on my 3...so yes it's a good thing
Nose dive is a characteristic of EBD. It is almost a side-effect. The real purpose of EBD is to allow for equal braking under different load conditions in the car. So if the back is heavily weighed down, it'll brake harder in the rear to balance out the front. When the car doesn't have load, it'll keep the nose up.
For the brake dust issue; this might not be a cause as cars without EBD are exhibiting the same condition. At the moment, the cause that I'm buying is that the rear brake calipers are too tight and are rubbing even while the brakes are disengaged. This can cause the excessive dust, accelerated pad wear and grooves from rocks/sand.
