W205 Brake Squeaking Sound Common?

[Gideon]

Recently sometimes when the brake was applied gradually, it gave off squeaking sound. As it was brought to the attention of C&C SA, was told that such practices would have squeaking sound. One has to step hard on the brake pedal to avoid such unpleasant sound. Of course, did not buy such advice & true enough after the car went through servicing with adjustment to the brakes, the car is as quiet as a church mouse. 

Wondering if anyone of you experienced such incidents or had nonsensical 'professional advice?'

They probably added some heat resistance lub behind the brake pad shim to eliminate the sound. Common issue and solution.
