My first repair the dealer replaced the front and rear pads at the same
time. Does the SBC by the distribution of power apply more pressure to
the rear pads causing them to wear the same as the front pads?
I think the dealer did you a great service... by doing both at the same
time, they eliminate you needing to come in the second time for the rear.
There is a reason why front brake rotors are massive compared to the back...
because the front does all the work.
When under ABS and ETS, they will grab whichever wheel they deem necessary
with more force to keep the car under control... but this mode is used only
when you need it so it is very minor wear to the rear pads.
No, as Tiger pointed out, the laws of physics still apply. When going
down the road forwards and stepping on the brake, the weight of the car
is transferred to the front axle. This means the front brakes do the
majority of the work and hence wear faster.
If the pressure applied to the rear was equal as you suggested, the
rear brakes would lock up, which isn't desirable.
