The way of tank braking is not limited to one method of using brake drums - the braking (braking) methods of tanks and armored vehicles include rolling braking, engine braking, brake braking and combined braking.
1. Rolling brake
While reducing fuel, depress the main clutch pedal, or put the shift lever in neutral, cut off the power connection between the engine and the track, and reduce the movement speed of tanks and armored vehicles with rolling resistance.
2. Engine braking
Without cutting off the power, reduce fuel or stop fuel supply to reduce the speed of tanks and armored vehicles by rolling resistance and engine braking force. Here, the kinetic energy of tanks and armored vehicles is consumed within the braking distance, and work is done to overcome rolling resistance and engine braking.
3. Brake braking
Brake braking is a method of embracing the brake drum (brake pad) with the brake band after the power is cut off, so as to achieve the deceleration or braking of tanks and armored vehicles.
4. Combined braking
Combined braking refers to a braking method in which engine braking and brake braking are used in combination. That is, without cutting off the power, reduce fuel or stop fuel supply, brake the engine, and step on the brake pedal at the same time. It relies on engine braking force, brake braking force and rolling resistance to reduce vehicle speed.
When combined braking is used, the braking distance is the shortest; followed by brake braking, then engine braking; and finally rolling braking.
Sudden braking is the killer feature of advanced tanks in China and the West. Because it is equipped with hydraulic automatic transmissions, such as advanced tanks such as 99A, M1A2, Leopard 2A6 and Leclerc, the switching time between emergency stop and reverse is very fast. It can fire backwards, and the maximum reverse speed is 30-40 km/h.

Russian tanks seem to run very fast, but in fact they are very clumsy on the real battlefield, reversing and speed switching are as slow as a snail. For example, the T-72 and T-80 tanks slow down from the normal driving state to zero, and then reverse at full speed, or turn around, and the conversion time is quite long, generally nearly 20 seconds. During this period of time, the Russian tank was very vulnerable, enough for our 99A tank to fire three shells at it.

The picture above is a company testing the sensitivity of the brake system of a tank. It is not ruled out that the picture is PS. It can be seen that the tank is moving fast, and when it is about to reach the crowd, the tank brakes urgently.

▲German Leopard IIA6 main battle tank demonstrates its high-speed emergency braking performance
The "Leopard" II tank uses the HSWL354 transmission with hydraulic brakes developed by Renke. Among them, the hydraulic brake has a maximum energy-absorbing power of 5,147 kilowatts (7,000 horsepower). The hydraulic brake and the mechanical brake together form the braking system of the "Leopard" II tank. This system can make the "Leopard" II tank weighing 55 tons The Leopard II tank brakes from a high speed of 65 km/h to zero in 3.6 seconds.
