Hey guys, just bought my 2017 C43 has super heavy air release sound after pressing break pedal. The sound came out when my foot is off the break, it will have the zizizi sound which really drive me crazy.
Is this normal to Benz?I took to dealership they told me it is normal, they cannot fix that.

Thanks!

I had this issue two weeks ago, had dealer advisor checked and they told me the brake booster needs to be replaced, and they ordered it from Germany which took them 10 days, this is covered by warranty, go get it replaced by dealer for free.
