Currently I drive a SLK32 AMG, but I am unsure if my next car will be a DC.
All of the newer models I "evaluated" had the SBC which was labeled
"parkinson brake" by me.
My first encounter with the SBC was in a E500 W211.
I first noticed the vibration and sound of the fluid pump for the SBC each
10 Brake pedal hits or so. (But luckily this was not noticeable in a SLK55
Also did I notice a little annoying delay from pressing the brake pedal to
the actual deceleration.
This could be described as a filter between the force on the brake pedal and
the actual force on the brakepads.
This filter may intentionally be implemented in the processing electronics
and causes quite noticeable group-delay and high frequency damping.
On a SL55 AMG I also tested the SBC was very similar.
If you kick the brake pedal hard, but shortly almost no braking happens. If
you do the same on a "conventional" braking system you get the wheels to
stop for a short time.
I don't like this slow reaction of the SBC brake, and labeled it "parkinson
On a AMG I expect not only the engine to be "impulsive".
I am not sure if DC can keep this "feature" up by saying "this is increased
comfort", especially on a AMG.
What experiences do others have with the SBC parkinson brake ?
