A Mazda mechanic once mentioned that the brake system is designed to apply the back brakes first, then the front if needed, which means the back brakes wear down more... but this seems absolutely excessive. Has anyone else heard this (or can anyone confirm if this is really how the brake system works)? Everything else on my 3 has been GREAT, but holy hell the brakes are frustrating!
Utter and complete nonsense. If that was the case, then every Mazda3 in the world would immediately spin into the ditch in icy weather. The reason the rear brakes wear so quickly is they are so much smaller than the front brakes.

As for why your particular brakes are wearing so quickly, there may be something wrong with your car. Our 2016 Mazda3 hatch has nearly 60,000 miles on the factory brakes.

Surely there must be some aftermarket calipers for the car.

No, no aftermarket calipers which are any different than the OEM calipers; at least not calipers which will mount to your car and give you a functional parking brake without a LOT of rework and money.

This doubled the pad life from 20k miles to 40 k miles but still that is not right. I think there is a design flaw. Might be something simple as the cable is too tight. Mine was made in Mexico and the build quality is not as good as my wife's CX5 Japanese made car. The pads are pretty thin when new compared to the front and that could be some of the issue. I don't think so because the rotors are starting to get a lip on them which indicates excessive wear. The brakes could also be equalized with too much going to the rear. I have been driving FWD 4 bangers for 30 yrs and never have I seen this.

It might help if you posted the recall, or a link to it. Sometimes they contain information which identifies the exact problem (or at least what they think it is).

GerryBuc I was surprised. Had I not brought it up, I would have wound up with the wrong parts. Seems parts catalogs defer to Mexico built cars. Shields up, guys!

Interesting, we have a Japanese built Mazda3.
