There are different quality of brake pads as well as brake shoes. With brake squeal, it is most commonly the front pads, but take a look at the calipers. clean any surfaces that slide on other surfaces, and look at where the pad balking plates meet with the calipers. Any slight vibration will cause a bunch of noise. There are a number of products designed to dampen the vibration of the backing of the rotor/pads, shims, and a type of glue called Disc Quiet (if I recall) which may make the noise quiet down. also pay attention to the rear brake shoes where they ouch the backing plate, this can also be a source of vibration or squeal. there are lubricants specially made to be used on those spots. NORMAL GREASE IS NOT A GOOD IDEA IT WILL MELT AND END UP ON THE BRAKE SURFACES OF THE SHOES AND DRUMS.
Also don't overlook a wheel that is not tightened or has dirt under it's mounting points, and wheel bearings that are worn out. Allcan cause noise
