rear brakes wear faster?

My rear brakes started squealing a couple days ago. I took out the driver side rear to have a closer look, I have a mm or less left. When I looked at the fronts, there's probably half or so of the pad left. I changed front and rear out at the same time about 24k miles ago. Why would the rear wear faster? Also, I noticed a slight slant in the wear pattern of the rear pad. What I mean is, when I look at the pad at a profile (from the side, long ways), there is more pad on the "left" than the "right." Anyone know what I mean? And why would this happen?

Thanks, in advance, for the feedback.

Yes, the rears wear faster than the fronts...

The FX has Electronic Brake Distribution which applies the rear brakes before the fronts to stop the front end from diving when braking.
 
You would think the rears would be bigger if most of the stopping power is done by the rears first, wouldn't you?

and the rear brakes always touchs even when released

Wondering why that is, cuz the wear indicator would cause squeal even when not applying the brake.
 
If im not mistakened, once the pad wears out to a point where the indicator pin will pop out of the pad and make contact with the rotor if your braking or not braking.
 
Wow, interesting to know! With every other car it is the opposite, the only time the rears wear first is from towing. Thats why I love this site, IS rocks!

You'll find this on most cars. It's due to physics - when decelerating the weight and energy transfers to the front of the vehicle, as a result front brakes are larger since they have more energy to cope with, and that extra weight also gives the front wheels extra grip and thus more braking ability.
 
Rear brakes engage first, but the fronts still do the vast majority of the work. As someone said, physics will cause the car to dive forward and down when you hit the brakes. Engaging the rear brakes first minimizes this, but the front still do most of the work. The opposite of this would be when you floor the car and the car rocks back and the rear and squats.

The rear brakes are used by slip and vdc, they apply the rear brakes in order to control your car or when they detect slippage. Like the awd system its always working and u don't feel it.

Braking bias is still mainly front brakes. Nothing has changed in that, just adding traction control.
