2015 Mazda3 Rear Brake wear

My 2015 3 is driven primarily in San Francisco - so it goes up and down hills a lot and driving is stop & go. The rear brakes had 2mm left after only 15K miles and 2 years of driving and were replaced. The 1217F rear parking brake recall repair was done in early 2018. Yesterday, after 4 years and nearly 25K total miles they tell me I'm down to 3mm on the rear brakes - that's under 10K miles to needing replacement! Front brakes have held steady and varied in measurement from 5 to 7 mm.

This car replaced a 2001 Camry that was driven under the same conditions and went 55K miles before the rear brakes were replaced.

So is this ridiculously fast rear brake wear normal for a Mazda3? The stock tires had to be replaced after 19K miles, so I'm thinking Mazda's using poor quality consumables.

Up front the rears will wear more quickly than the fronts, like 2:1 in my case over 4 Mazda3s of this era. I would say the rears should last at least 30-40k miles mixed city and interstate driving...but where I drive there is nothing but flat!

Cross-posting from the 2016 thread....

I have a 2015 Hatch, and I've felt like I've been just demolishing rear brakes for no reason. (My last pair only survived about 12,000 Miles!) 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!
