wearing out brakes

My front brakes wore out in 15 k miles and i have factory pads and rotors. Im easy on the brakes but i also do all city driving. i have 33 inch tires and i know thats probably most of the problem. im just wondering if anyone else is having the same issue?

 

Are they dragging? They should last damn near 40k to 60k miles.

 

at this point I dont know. i guess ill have to check if the calipers are locked up or if the brake fluid is flowing right. and the other thing is my rear dont last that long either, ive gone through half the pad on the shoes in the last 20k miles.

 

Welcome to my world haha I go through brakes every 15-20k miles
