Rubbing sound turning slightly left and sharp lefts

If this just started after the parts were replaced, there are two common things to consider. The first is the brake rotor's splash shield got tweaked and is rubbing on the outer edge of the rotor. That can usually be bent back by hand, otherwise a small pry bar will do it. Second, if you have the rotor design that slides onto the hub and wheel studs, there should be a light coating of high-temperature brake grease applied to the hub where the rotor's center hole makes contact. GM has more trouble with this on their front-wheel-drive cars, but any vehicle with this style rotor can develop a crunching noise when cornering, or a rubbing sound. It is caused by the very minute flexing of the wheel and rotor from the side forces when cornering.

If neither of those seem to apply, there is a tool you might be able to borrow or rent from an auto parts store that borrows them called the "chassis ear". It is a set of six microphones, a switch box, and headphones. You clip the microphones to suspect points, then drive around while listening with the headphones. You can move the microphones around to zero in on the source of the noise. Be aware that many mechanics have never seen or even heard of this tool. Suspension and alignment mechanics use it to find rattles, squeaks, and other noises.

Another thing to check is the brake line, if it was twisted or moved it may flex the caliper a bit and cause it to rub. Also check that the caliper is able to slide freely, if it is binding even a bit it could cause a pad to drag and when you step on the brake the pressure on the brakes stops the noise.

Please let us know what happens so it will help others.
