I have a jetta 2002 1.8

What is your question?

This morning I turn on the car and every time I pressed the break pedal my car start shaking and making noise like if I was in a road full of rocks, then I make the change to a NEUTRAL and stop shaking, then the light turn green and I have o continue driving but the car was prety much slow, and I feel the vibration on the breaks foot. I get home I turn it off and 1 hour later I turn it on and I put the reverse and when I take my foot off the brake , a strong noise like a hard metal broked, and I feel the vibration on the breaks foot. please help me to find out if it is safe to drive the car to the technician. thank you.
