A few suspension/brake related concerns plz help

Dclark137

So I have a few concerns with my beautiful silver 370z:

When I brake (not heavily) and am in the process of switching lines or if there is any grooves in the road the wheel pulls hard in different directions. Like as if its the opposite of torque steer in front wheel drive its like brake steer or something.

Also noticed a slight vibration when braking at speeds around 70/80 when light braking. Kinda comes through the wheel but I can feel it in the peddle I think too. Is that just the abs pulsing. I have the sport brakes.

Lastly, when I turn the wheel hard left or right when turning line trying to 3 point turn or any time the wheel is relatively sharply turned it creeks/bumps its hard to explain but it's like the wheels are going over a gravel lot.

Any help or ideas what these maybe or if they r all totally normal and I'm just a over protective daddy let me know.
