There is no sound if they are in good working order.
Dirty brake pads could cause a car to make a squeaking noise when putting the car in gear or when releasing the brakes. Cleaning, sanding, or replacing the brake pads should make the sound stop.
Possibly nothing more than the brake pedal return spring catching on something.

brake shoes or pads are worn and need replacing
the roder is the part of the car that the brake pads or the brake shoes squeeze to make the car stop :)
sounds like your brake calipers could be sticking.after a short run feel your rim if it seems overly hot that's probaly what it is
you need brake pads
There are several things that may make your brakes squeal. The most common causes are a lack of lubrication and worn brake pads. Less common (and not all agree that it is a cause) is dust and grime in the brake system. The best thing to do is to take your car to a mechanic and have your brakes checked and make the necessary repairs.
It does not make a difference if the car is hot or cold when you add brake fluid.
Have your brake pads checked. If the squeaking sound stop when you apply the brakes it may be your brake pad wear indicators rubbing the rotors to warn you to have your brake pads replaced. If you ignore it damage will result when the rotors and metal brake pad backing or rivets rub after the brake pad linings are worn away.
I assume that you have rear drum brake. If so, the knocking sound which happens only when apply the brake is more likely cause by an out-of-round drum. Take your car back to the mechanic that installed them. This problem is not bound to go away.
I hope you take it to a garage and have the brakes inspected. Might be a brake fluid leak.
