What part of brake system causes brakes to squeal? Pads, rotors or calipers?

Pads have a small metal strip on them as a wear indicator. when you hear the squeal its time to replace them.

Pads have a small metal strip on them as a wear indicator. when you hear the squeal its time to replace them. that will sure do it also, and it happens way less often, if the break pads are just fine, you can glue them on to the pistons in the calipers, (they sell special whatever it is in the auto parts store for that use) and that stops the resonance that causes them to needlessly squeak |

Pad wear indicator will be a more constant fingernails on chalkboard kinda kind of squeal. Its just little spring that when pad wears down, starts scraping on the rotor. If rotors are bit warped, and pads trying to move around, then you just get squeaky noise just when you apply brakes.
Hopefully you havent just wore pads down to metal backing plate. Thats a horrible low pitch grinding sound that means $$$! Cause most likely you will have to replace the rotors along with the pads, possibly calipers too. Should notice this cause braking will be significantly diminished.
Some cars you can see pads without removing wheel. Some you have to remove the wheel to see pad wear. You can definitely see pad/rotor wear by taking off a wheel. Look at both pads on each wheel, sometimes caliper doesnt apply force evenly so one pad will wear significantly more than the other. With single piston caliper, or caliper with two pistons on one side, means caliper isnt floating on its perch. On say four piston caliper, the pistons on one side are sticky or rusted, moreso than pistons on the other side.
