there is a noise in the steering column when I apply the brakes.
You need to provide a lot more detail before we can help you.
There could be something loose in the front suspension/brakes/wheels that is transmitting a vibration up the steering column. This should be taken carefully to a competent mechanic and soon.
It could also just be the unlocking motor running when it shouldn’t. That’s why we need a lot more detail, like, what the noise sounds like maybe?
