YEP!
It may be the brake pads moving slightly inside the calipers. If the noise also happens when going over bumps, check the shims.
Usually they are just used to prevent brake noise (squeaking etc.) I was told that the shims should be used to set space tolerances between pads and rotor, if so, at what measurement? I have no idea!
Brake squeal or whistle is Vibration, from forcing the fixed pad against the rotating rotor. Metal shims and lubrication on the backing of the pads allow for this vibration greatly reducing noise. A tight fit between pads and their mountings is also important as is the material of which the pad is made. Most annoying brake noise may be traced to lack of shims, lubrication, loose fit or brake pads not meeting the OEM standards.
You need to check the brake pads to see if the brake pad shims are broke, missing or loose. This is most likely the source of your noise.
'Shims' are more often called anti-rattle clips when used with automotive disc brakes. This is because as the brakes are used the clearance behind the brake pad increases and allows the brake pad to vibrate and cause a squealing, sqeaking , etc. If clips or shims where used, or are included with your replacement brake pads, do use them.

Sometimes you can git rid of that noise by just changing the brake pads to a different brand or style and sometimes you need to resurface or replace the brake rotors and brake pads. Be sure the calipers slides and caliper pistons move freely. Some brake pads require shims and/or anti-squeal adhesive/lubricants. Consult your local auto parts store as to what they recommend for their brand of brake pads.
Put the car on jack stands and remove the wheels. Locate the calipers and brake pads and remove the pins and clips from the calipers. Slide out the old brake pads and push the piston back to make room for the new pads and shims. Slide in the new pads and shims and put the pins, clips and cotter pins back in. The front and rear replacement process are very similar, but have different pads and shims.
Check for bent brake backing plate or anti-rattle clips, abutment clips, or pad shims that are broken, bent, missing, or slightly out of position.
The starter drive gear will be too close to the flywheel, causing a grinding noise when the starter is engaged.
Disconnect battery. Then the electrical connection on the starter solenoid. Remove the starter bolts and the starter. Note the location of the spacer shims. Installation is the reverse. Don't forget the spacers shims or you will get noise when starting the vehicle.
