- Braking time is the amount of time it takes for the vehicle to come to a complete stop after the brakes have been applied. Braking time depends on:
-
the force with which the brakes are applied
-
the condition of the brake linings and drums
-
the traction of the tires on the road surface
-
the vehicle weight and speed.
Braking distance is how far a vehicle travels during this time.
Total stopping distance is the sum of perception distance, reaction distance, lag time distance and braking distance.

-
When applying the brakes, press down the pedal using an even pressure and then ease off the pedal as the vehicle slows down. Just before the stop, release the brakes to avoid a sudden jerk or rebound. Then apply pressure to the brake pedal again to hold the vehicle while it is stopped.
-
Do not fan (alternately applying and then releasing) the air brakes as this wastes air pressure. Fanning the brakes on a long downhill grade may mean that you do not have enough air pressure for the brakes to work properly.
-
Avoid using the brakes too much going down hills. Downshift before going over the top of the hill. Use engine compression as a way to control your speed on steep grades.
-
If there is a low air pressure warning, stop as soon as possible in a safe place. Increase the air pressure before continuing.
-
Before going down a hill, test the brakes. Look at the air pressure gauge, apply the brakes, and check for abnormal air pressure loss. Do not proceed if there is abnormal pressure loss. |
