Any motorist has to be able to define a brake way. Safety of the driver and those who are in the car besides him sometimes depends on it. What is a brake way and as to define it to avoid troubles on the road?

1. The brake way is a distance which the car passes after operation of the brake system and to a final stop. The size of a brake way depends on a set of factors: speeds of the movement of the car, the way of braking and conditions which are set the road. The more speed, the is more also a brake way.
2. Besides the designated factors the paving and its condition, weather, mass of the car and also technical characteristics and serviceability of wheels and the brake system are most important. Length of a brake way will be the smallest on the dry asphalted road, the greatest – on ice. Respectively, together with increase in a brake way the danger increases.
3. Of course, in emergency situation to calculate a brake way extremely difficult, but it is necessary to present to a possibility of the car in this plan correctly to orient at the right time. There is a formula by which it is possible to determine a brake way. Motorists are recommended to use it before taking the wheel as it can prevent many undesirable incidents.
4. The formula looks so: S = Ke x V x V / (254 x Fs). It is necessary to explain the symbols used in it. S – it is length of a brake way in meters, Ke – braking coefficient which for cars is always equal to unit, V – the initial speed when braking which is measured in km/h, and Fs – the coefficient of coupling with the road depending on its state (at dry asphalt – 0.7, at the wet road – 0.4, in case of the rolled snow – 0.2, and 0.1 if the road is covered with ice). Definition of a brake way – the simple and useful effect available to each motorist. It is enough to substitute in a figure formula, corresponding to a specific situation and parameters of your car.
