When descending a long, steep downgrade, using the proper braking technique is crucial for maintaining control and ensuring safety. Applying the brakes until a definite slow down is felt, and then releasing them, allows the driver to utilize a technique known as "brake modulation." This method helps prevent brake overheating and fading, which can occur if the brakes are held continuously or applied too aggressively.

By intermittently applying the brakes, the driver allows the brake components to cool, thus retaining their effectiveness throughout the descent. This approach balances the need to slow the vehicle with the preservation of control, reducing the risk of losing braking power when it is needed most. It is essential to stay aware of the vehicle's speed during the descent, adjusting braking as necessary to maintain a safe and manageable rate of speed. This technique also prepares the driver to respond effectively to any unexpected conditions that may arise on the downgrade.

Using only engine braking can be effective in certain situations but may not provide sufficient control alone, especially on steeper grades. Waiting until reaching the bottom of the hill to apply brakes can result in excessive speed, significantly increasing the risk of losing control. Continuous application of brakes could lead to brake failure due to overheating. Thus, the chosen technique of applying brakes until a definite
