As mentioned this is becoming common on many platforms

Electric brake force distribution along with stability assistance systems. Will often apply the rear brake more than you might have expected

Some fwd appliance cars will still wear out front first. But quite a few today do not

Think of it this way. The car is now braking alot smarter and using more of the capacity

As others have said this is completely normal on modern vehicles with stability control systems because rear bias is more stable in light braking. Our minivan is the same way. I thought something was wrong but it was working as designed. You would think manufacturers would compensate for this increased wear with bigger rear brakes, but I guess if it's not a safety issue they don't care.

I doubt it's that they don't care, it's more likely that larger diameter and heavier rotors means lower CAFE.

Appliance car. Toyota Camry. Ford fusion. Explorer (not st) Nissan Altima. Etc etc

Commuter car whatever.

Now the brake thing. If you are optimizing then the front brakes still do more work. The part that I don't think is explained well. Is that stability assistance flutters the brakes as needed when needed

For a rwd or even a mostly rwd device. This is also traction assistance. Remember you have an open diff. So anytime there is a little extra spin when putting down torque. Flutter a rear brake

And it will do this or attempt it first. Before putting in 4wd for those with 4wd auto. So the brakes are used alot more than most think

I'd never heard a vehicle referred to as that before. I guess all vehicles are appliances, as they all have a specific task: to get us to where we want to be, from where we are

I just had to replace my rear pads at only 48 000 km last month, the inside pads were less than 5% and out side pads had atleast twice if not 3 times that left. The fronts are still atleast 70%. I've never owned any vehicle where I've touched brakes before 100 000km. Idk if it's the trac control or advance trac or mabe it had something to do with always driving in tow haul ( I've read some things on here) and im sure the heavier tires dont help. Granted I'm by no means gentle with my truck but I was shocked by just how fast the rears wore out. In my experience I've always done fronts first. Now I just stick with sport mode lol. It's comforting to know that it's fairly common to burn thru the rears tho. Oh how the times and technology have changed lol. Atleast its super easy to change them.... once you learn about the electric parking brake service mode. This fourm has an abundance of knowledge! Big ol thanks to all the participants on here

I'm not sure John Force would appreciate you calling his "hot rod" an appliance.

That's a HUGE sign that your sliders ain't a-slidin'. When the pins get stuck, the caliper doesn't slide on them to pull the outside pad towards the rotor, so the inside pad does all the work and takes all the wear.

Probably not, but I'm just the messenger

Of course, I should be more worried about Ken Block, as his wheels adorn my truck, and he's not 73.

Look back at my reply #9. Stuck slide pin cost me front Pads and two front discs for proper wear balance repairs.
The stuck right side caliper was able to be lubed and remain in service.
The rear brake operation is very noticeable at low speeds and reduces as speed rises.
You have to understand that rear braking makes the vehicle more controllable for quick stopping and helps straight line the vehicle rather than have the fronts do all the stopping and risk the rear coming around to say hello!
You have to come up the times, and let go of the old.
Even towing, it is preferable to have the trailer brakes come in early and start braking first to keep everything aligned.
Same principle.
I believe there are now optional OEM rear pads that may have larger surface areas and last a bit longer.
There should be no more beating this subject to death with the info shown in this thread.
Come up to times with it!
If there is an obvious wear issue, then something is wrong or has not been done properly.
