A couple things you can check & try... are there anti-squeal shims
between the pads and the pistons? If not, try to get some and install.
Even with the shims, it's a good idea to use an anti-squeal product that
sprays on or is spread on or is peeled and stuck on the back of the
pads. See your local auto parts store.
It also sometimes helps to chamfer the leading edge of the pad (that's
the edge the rotor enters first during normal forward wheel rotation).
It can get sharp as the brakes wear. Just use a file and put about a 45
degree angle across the edge, about 1/16 to 1/8 inch wide. This is
especially useful with newer pads that squeal.
You might also take rotors and pads out & check for glazing. If too
smooth and shiny, take down to machinist and have em just wipe the
rotors to break the glaze. You can carefully use sandpaper to do the
same on the pads.
Try a different type of pad. I never get the cheaper pads, often the
better ones are less prone to squeaking due to better formulations
and/or built-in anti squeal shims, etc.
