Drum & Disc are the two types of braking systems on a car.

Assuming you mean "braking", aggressive braking.
ABS??
Hydraulics.
The braking system makes a car stop.
Assuming that braking force is the friction force; F=m*a 4000 = 1000*a a = 4 m/s^2
If your car vibrates when you are braking, you might have pads that have worn unevenly. You can have the brake pads inspected to see if there is wearing on the drum or if you have a problem with your rotors.
The sound of the braking railroad cars shreiked through the night. Now matter how hard he pushed the pedal, the car was not braking.
