Also had the front arms and bushings replaced about 20k miles ago so they should be good

You could pick up a cheap set of run-out dial indicators from say Harbor Freight. Remove the front wheels and check the run out on the brake rotors as you turn the rotor by hand.
You might also remove the brake rotor and check for rust(buildup) between the brake disc and hub. This area should be shinny new steel... and NOT rusty. You could use a flex disc or angle cutter with the correct disc(or 3M scotch pad) to clean up the hub and rotor. You don't want to use a wire brush as this doesn't remove metal, it just polishes it up. You want clean, fresh, flat steel for the rotor to sit flush on the hub. Many people skip over this step when replacing their brakes.

IF it's warped brake rotors... you will feel a vibration/pulsation in only in the brake pedal.
IF you feel the vibration in the steering wheel(only under braking!) & in car(seat of your pants)... it's a worn suspension component, like the thrust rod bushings.
