Brakes are available as disc or drums; older vehicles tend to have drum brakes while new models incorporate disc brakes. Both systems use friction and resistance to bring the vehicle to a stop. The job of the suspension system is to maximize the friction between the tires and the road, as well as provide stability to the steering system. The steering system takes the rotation of the steering wheel and converts into the swiveling motion of the wheels.
All three of these systems are vital to the safety of the vehicle. BEDO provides training systems regarding all of these topics using real-world components to get in touch with the realistic systems.
