New Jersey Air Brakes Practice Test

What does stab braking involve?

1. Pressing the brakes and holding

2. Applying brakes fully and releasing when locked

3. Gradually increasing brake pressure

4. Only using the emergency brake

The correct answer is: Applying brakes fully and releasing when locked

Stab braking is a technique used primarily in emergency situations when an immediate stop is required. It involves applying the brakes fully until the wheels lock, and then releasing the brakes to allow the wheels to regain traction before applying the brakes again. This method helps to maintain control of the vehicle while slowing it down quickly. By locking the wheels momentarily, a driver can maximize braking effectiveness until control is regained, at which point the driver can reapply pressure. This technique is particularly useful for vehicles equipped with air brakes, as it allows for better control over stopping distance and ensures that the braking system operates efficiently.
