The whistling sound made by your car could be caused from brake dust. Another reason may be from a bad wheel bearing that needs to be replaced.
Possibly a bad wheel bearing.
There are a few causes to whining brakes in a car. One reason could be that the caliper is out, and another could be that the pad is worn out.

Master Cylinder seals are defective. Replace the Master Cylinder ASAP. Stop driving the vehicle until you have this repaired. The brakes can fail completely at any moment.

Yes, applying the brakes on a bicycle should slow it down. Little squares of rubber are pressed to the metal rimming on the bicylce's wheel when you pull a handle brake, or pedal backwards (depends on if it's an adult bike or children's bike).
if they are drum brakes it could be that the drums friction surface has a defect on it and everytime the shoes hit it it pops or it could be a bad hold down or quieter spring in the drum itself
