I have a 2015 mazda 3 with manual transmission and 23,000 miles on it.

My rear brake pads are shot, with wear indicator whining loudly, and the rear rotors are nearly shot.

However the front pads & rotors are fine...

Normally with my driving habits, I get 50-100k out of front pads, and 100-150k out of rear pads. So for the rear pads to be completely worn down in 23k miles is disconcerting.

I took it to autotire, and the dealership, neither has any explanation for why the rear pads wore out so fast. Both claim the brakes are not dragging as far as they can tell. The dealership of course is committed to the idea that I simply wore them out, ie: no waranty repairs.

Has anyone else had this issue?

Also, this model has an anti-rollback braking action specific to the manual transmission (prevents the car rolling backwards when stopped on a hill, for about 1 second, allowing you to transfer your left foot from brakes to clutch easily). I can't help wondering if this is somehow responsible?

Any thoughts?

 

Rear disc brakes wearing out before the front brakes has, in my experience, been an issue exclusive the a number of Japanese brands; Hondas seem to be the most common cars with this type of complaint.

FWIW, my wife's 2012 GTI has the anti-rollback braking and she still has some pad left after over 55,000 miles.
