Anyone has experience with issues related to brake boosters- specifically the rubber grommet. Some not so obvious hissing sound after release of brakes. I am a bit of sensitive to sound so its irritating to me.

Is it safe to continue driving. My temp fix is to apply grease on the grommet and the sound disappears....Comes back when the grease wears thin
