Brake lag distance is primarily affected by which of the following?

The vehicle's speed
The weather conditions
The type of brake system
The driver's reaction time

The correct answer is: The type of brake system

Brake lag distance refers to the distance a vehicle travels while the driver reacts to a situation and applies the brakes. The type of brake system directly influences how quickly and effectively the brakes can be engaged, which in turn affects the brake lag distance. Certain brake systems, such as air brakes in larger vehicles, differ significantly in their response time compared to hydraulic brakes commonly found in smaller vehicles. For instance, air brakes may have a longer lag time due to the time it takes for air pressure to build up and engage the brakes, whereas hydraulic systems may respond more quickly. This element of the brake system is crucial in determining how efficient and responsive the brakes are, which impacts overall stopping distance in various driving scenarios.
