Brake noise

[Operator23]

I have a 67 Barracuda with power disk brakes up front. It just started to make a noise when I push the brakes all the way down...kind of a constant whine/siren sound until I let off the brakes a little. Any idea what that could be?? Thanks for trying to help.

Probably either pad vibrations, wheel bearing or even could be the tire rubbing on a ball joint when braking.
Guess you'll have to pull the wheel and find out.
