I am noticing some vibration when I put the brakes on while driving at highspeed on 2003 Volkswagen Beetle

Is this likely to be due to need for alignment? or more likely a brake issue? I know I need an alignment but am wondering about the brakes as well..Sometimes driving in traffic you have to stop suddenly and this is when it is most likely to vibrate a bit..

Could be both. Most likely cause is a warped rotor causing the vibration.
