I have a 2014 Cadillac SRX and there is a metal to metal noise coming out of the front end. I have replaced the rotors, brake pads and the wheel bearings were replaced about 6 months ago but, the noise is still there. I have taken the brakes apart several times to use a brake squeal lube on the pads, verified that the calipers aren't damaged and that the anti-rattle clips aren't touching the rotors but, I am still hearing the noise. I have noticed that when I turn the wheel to the left the noise stops then, when the wheel is straight or turning to the right the noise continues.

I have also replaced the brakes on the rear of the car but, based on where I hear the noise and the fact that turning the wheel does or doesn't stop the noise I believe it to be in the fronts brakes.

I am out of ideas as to where the noise may be coming from.

Yes I think so. Look at the Constant Velocity Joint at the front axles - both sides. If worn out, then joint is metal to metal without appropriate lubricant. If the noise occurs when driving, this is a likely candidate.

It turned out to be the rock shield behind the rotor touching the rotor.
