This isn't really a problem as far as I can tell - just curious if anyone else notices the same thing.
I am in 2WD probably 98% of the time, but with cold and snowy weather I've been using 4 Auto more often lately. I've started to notice that the brake pedal seems to have a little bit of dead space, but only in 4WD. Best I can explain it is if you press the pedal, you get maybe 1 inch of travel where it feels like there's almost no resistance, then the rest of the travel feels normal. The transition between the dead space feels almost like a pop. If I switch to 2H, that dead space goes away. In either 4A or 4H it's there. It also might only happen when it's cold out, like below freezing - I need some more warmer weather to confirm that.
My truck's a PowerBoost so I'm wondering if it might have something to do with regenerative braking when the front axle is driven vs free.
No issues stopping and it's entirely possible the truck has done this since new - last winter was a dud, so I barely used 4WD.
