You might have 2 issues here. If it shakes without your foot off the brake the tires need balancing or you have a bad tire. The shaking when you touch the brakes is caused by warped rotors. You will need to have the rotors resurfaced. Acura does reccomend doing this with the rotors on the car. If you go have this done at a place other than the dealer be sure they resurface the brake rotors on the car.
Thank you so much, I'll try your advices.
Glad to help
