What is the first step of the threshold braking technique in vehicles that do not have anti lock braking systems?

The first step of the threshold braking technique in vehicles without anti-lock braking systems is to apply the brake pedal firmly but gradually, aiming to reach the point just before the wheels begin to lock up. This requires the driver to feel for the threshold of braking force where maximum deceleration occurs without losing traction. It's essential to maintain control of the vehicle by modulating brake pressure to avoid skidding. This technique enhances stopping efficiency while preserving steering control.
