Is a small hissing noise from brake pedal normal?

Don't get me wrong.
I still think for the money W205 offers a lot of stuff.
Design in and out is great.
A most comfortable ride in the class with the best space in the class too.
However, reliability wise... it is worse than VW products... lmao

funny that MB thought little hissing is OK but mine is just a tad louder so they said they will replace it so well see what they do..
but im surprised that they have to be told what to replace in order for them to actually do it..like if I was like "ok that noise is fine' they wouldn't even replace it..
I still have that crackling, rattle sound from the above compartment where the sunroof buttons are and where you put your sunglasses, and they said they tightened the harness up there with some tape but yet its still like that

So I reached out to MB corporate to complain about the many issues this cpo had in a little over a year owning it, I was told that a executive referral manager will contact me...I would not mind getting into a 2019 lease if they take this back , but for the record the dealer does correct each issue under warranty that does come up ...

Got my car back today , brakes work great with no hissing but what I find strange is that the car feels like it runs better or smoother and accelerating better . Could the booster be related to this or is it just my imagination lol

its funny you mention this because my c400 feels soo heavy and seems like doesn't have that jump from get go like a c300 loaner I got..maybe cuz I have 19" winter studded run flat tires? but the 2018 c300 loaner I got had Pirelli run flats on them I dunno if it was winter tires or all season, but the reason for my comment is my brakes make that hissing noise and MB has ordered the brake booster replacement part so ill see once mine is replaced and my car has that extra jump to it in terms of acceleration

haha no it isn't your imagination, its funny cuz I read your comment and was waiting to see if mine was same and it does feel like it accelerates better, has a jump right off start and brake pedal is smoother and software where I don't have to push as hard to brake..

I can't find mine otherwise I would post it but I don't understand why dealer is giving you problems. There shouldn't be any hissing noise coming from pressing the brake pedal, that's it. When i took my car in, they were like yeah that noise is the break booster. Easiest warranty repair ever...

ya I don't know the part number either on mine, but they shouldn't need a part number just tell them the brake booster needs to be changed. they may push you around like they did with me 1 or 2 times but they will replace it the third time you complain about it
