Drum Brake Unit

The Drum Brake Unit, allows the study of the forces acting on a drum brake, the difference between the braking torque of the primary shoe and secondary shoe braking systems and determining the coefficient of friction between the drum and the brake shoe, also with the equipment the different types of configurations of existing shoes can be studied.
