The braking distance is how far a car travels after the driver applies the brakes. This distance depends on the initial velocity and mass of the car and the size of the braking force. The total stopping distance is found by adding the thinking distance to the braking distance. Stopping a Car

The distance for a moving vehicle to stop on a clean dry surface, not including any mechanical failures, perception problems of the driver, reaction time. The distance needed is increased with speed, poor road surface or any other non-ideal conditions.

The distance between the point where braking starts and ends.
