if it's the back and they're single action calipers.. check the sliders are.. errr. sliding..
May have to pull it apart.. clean up, and a drop of copper ease on the slidey, shiney bits..
They can get mucky and stick/hang causing the caliper to twist a tad when the brakes are applied.. vibration.. squeeeeel..

Mine squeal too. I have decided that it is just what V6 fronts do.

I tried taking it up to 100mph and standing on the brakes - hard.

Yeah - next time in town it slowed down with no squeal. Success.

The time after - bloody squeal again.

I'll live with it.

Member car:

GTV 2.0

The smaller the vibrating object is, the higher pitch the squeal.

As I understand it:
really high pitch squeals are caused by the pad corners (chamfers may fix this)
high pitch squeals are caused by the pads
medium pitch squeals (under 10kHz) will be the calipers vibrating
low pitch squeal/graunch is when the whole upright assembly vibrates

Car manufacturers add mass (more weight) to the calipers to tune out the squeals, so just be happy that AR/brembo have not done this as the car is heavy enough already...
