Question on SBC
Hello all,
I have some strange experience with my brakes on '06 4Matic. Once in a while, I hear some kind of air leaking noise when I step on the brake pedal. It's not SBC buzzing noise I am familar with. Whenever I hear this noise, the feel of the brake is definitely different from normal status. This happened only few times. I think it was 5 times over 2 year period. I took my car to the dealership to have it checked, but couldn't repro the noise there.
Does anybody know if this is the symptom for brake failure or have similar problem?
Your expert opinion would be very much appreciated.

Does anybody have some detail on a backup hydraulic-only braking system? It seems to me what I have experienced was SBC failure. Of course, there is no proof for this since there is no error message at all.
Sir Konigstiger? What's your thought on this?

Can you describe more what happened? I cannot think of an SBC failure without any malfunction indication (never say never though).

When I read about the "backup hydraulic-only braking system", my gut tells me that what I have experience could be it. Maybe I am wrong
