Peak brake efficiency is reached just prior to what event?

Peak brake efficiency is reached just prior to locking up the wheels. When a vehicle is braking, the goal is to maximize the friction between the tires and the road surface to bring the vehicle to a stop as quickly as possible. This maximum friction occurs right before the wheels completely cease to rotate, a state known as "locking up."

At this point, the tires are still under some level of rotation, which allows for optimal control and braking effectiveness. If the wheels lock up, the vehicle can enter a skid, leading to a loss of control and increased stopping distance. Therefore, understanding that peak brake efficiency is achieved just before this critical point highlights the importance of precise braking techniques in emergency vehicle operations. This principle is essential for drivers to maintain control while maximizing braking performance, especially in high-stakes situations.
