Put konis on my car recently and afterwards the brakes are chirping while driving and during braking it sounds like a thinking noise as the car slows. I popped the rotor off the driver side and some rust had gotten knocked loose behind the hat and I cleaned it off and it was fine. I did the same for the passenger side and the noises persist. Any other suggestions? Everything's tight. Nothing broken anywhere. Front brakes , just new struts, used OEM springs
