Why does my analog data lag the built-in accelerometer data?

Hello,
I have a DL1-Pro and am logging GPS, internal accelerometers and analog input #2 which is connected to a ribbon switch
taped over my brake pedal. While doing some braking testing I noticed that the built-in accelerometer signal reacts before
the brake pedal switch is pushed (see attached .jpg).
In the setup of the DL1 accelerometer I left all the "Maximum rate of change" and "Smoothing Filter Time" parameters set to the default "0" values.
I doubt that the car started decelerating before I hit the brake so is this an anomaly of some built-in filtering of the built-in accelerometer signals?
Thank you,
Jeff.
Long time user - love my DL2 and DL1-Pro.
