So my brakes have developed this, sort of a croaking noise, but only when easing on the brakes or letting off them. It's been a few months since I've had the car looked over to make sure everything is in working order and at that point it was said my suspension was fine: control arms, bushings, etc. Nothing looked out of the ordinary. Any idea with anyone who may have experienced this? Again, it's a light croaking noise that feels like knocking when easing on the brakes, and goes away with more pressure applied to the brakes. It then will croak when I ease off the brakes.
