Acceleration and deceleration

I want to make character which smoothly starting running and smoothly stopping to idle.
In first case I set “Max acceleration” to 1000 and it works good but when I try set “Braking deceleration” to any value it seems to have always the same behavior for every value (1 or 1000 it doesn’t matter). My character always immediately stop…

Have you any idea what I’m doing wrong?

+1 for this. How come deceleration doesn’t work?
