Before the update I was able to "trigger" the increase in braking force fairly easily. I found that you could set it off by doing a quick, but light footed, jab on the brake peddle. The brakes become super sensitive until you release your foot completely from the brake for a second or touch the throttle.
Haven't been able to recreate it since the update. The car feels much more solid now. I'm surprised how much better the driving experience is. Note I'm doing mostly city driving.
