I have a 2011 Toyota Camry with 120,000 miles on it. I have had to change the rear brakes 3 times in the life of this car, but the front brakes are still great!?! Does anyone have any thoughts on this? Is there something to this that I should be worried about? Please let me know...

 

Car makers can design a brake system to wear more on the rear then front or visa versa.

This seems to be normal for this year (generation) of car.

If the braking is normal, don't be worried.
