While braking, at time the front end will vibrate/shake. Brakes look fine.
although your brakes look fine, your rotors are probably warped and need replacing. change the brake pads with the new rotors. i would guess the harder you brake the worse the vibration is. and if you brake gently it is not as bad.
Don’t buy cheapo brake pads and rotors
do NOT buy Wagner brakes
Also no store brand brakes
When you order your brake components, ask for components that meets/exceeds the vehicle manufacturers specifications.
