97 olds 88 Caliper Issue

Car stops good when it’s cold but once it’s had time to warm up and I’ve engaged the brake a few times, the steering wheel shakes, feel like the caliper also doesn’t want to retract after I push the brakes in. I’ve got new rotors and pads on this but I’m over here still putting my pedal to the floor to properly stop. Am I nuts thinking this is my issue or could it be something different from what I’ve said above.

The slider pins on the caliper could be binding, rotor has excessive run out, no set answer here, you need to check it out.
