What happens when you step on the brakes?

In a manual brake system, the pressure from your foot increases the pressure in the brake lines and in the brake cylinders. The clyinders expand and press the brake pad or shoe against the brake friction surface (a drum or a rotor) increasing the friction and causing the wheels to stop or slow. In a power brake system, your foot pressure is enhanced by the power assist on the master cylinder to make stopping easier.


Covering the brake is the same as riding the brake?

For example, while proceeding through a traffic light, you would want to take your foot off of the gas pedal and place it just above the brake pedal (without applying pressure) to decrease your reaction time in case you need to brake suddenly.
