Coefficient of Friction is the representation of the ratio of the force required to move one object over another against the force preventing the opposite motion. It has a very critical impact on the performance of the braking systems and the clutch systems of an automobile. If a car is parked with the brakes applied, then the coefficient of friction is the ratio of the force required to move the car to the weight of the car sitting on the tire tread touching the road surface. If the coefficient of friction is higher the better the grip. The friction between the wheels of the vehicle and the road surface can easily determine the stopping distance and the acceleration power as well. Assuming that the braking systems and the tires of a vehicle are well maintained, the minimum stopping distance of a vehicle is determined by the effective co efficient of friction. There are two types of co efficient of friction. They are coefficient of static friction, coefficient of dynamic friction. The amount of force required to move a vehicle is proportional to the vehicles weight. The more the weight, the more power would be required. When the co efficient of friction is lesser, the vehicle can accelerate at great speeds by encountering lesser resistance. The factors of the coefficient of friction are taken into consideration while making automobile tires as well. Advanced braking systems also consider the coefficient of friction while designing the braking systems. When trying to determine a vehicle's brakes, friction coefficient the fluid pressure required for the brake pad, and the torque are considered. Regular Original equipment manufacturer brake pads are equipped with a lesser coefficient of friction than the high-performance brake pads. Higher braking force does not require lots of fluid pressure if the friction coefficient is high.
