Just replaced the rotors and installed new brake pads, is there anything else this could be besides the warped rotors? Checked out the ball joints for excessive movement and there is none/this statement was also verified by my mechanic when he had the car on the hoist.

It could be the rear brakes. Did you replace all four rotors/drums?

New rotors could be faulty as well.

Have them checked for run-out.

Thanks-all the brakes were replaced, wheel cylinders, hardware the works so is it a pretty safe assumption that I have bad/faulty rotors? Thanks I will have the run checked out

Recheck the rotor installation if there are any run out. Ensure the hub surface is clean ad free of rust. Any accumulation of rust on the hub surface can result in the rotor not seating correctly.
