A tactile feedback device (TFD) drum brake has a drum rotor that creates at least two gaps and at least four shear surfaces. Magnetically responsive (MR) material is disposed within the gaps. The TFD drum brake further has an upper and lower magnetic seal to prevent the migration of the MR material from the gaps. The drum rotor is thin and rapidly saturates when a magnetic flux is generated. Controllable torque is created when the drum rotor is saturated. The controllable torque provides feedback to an operator of vehicle with the TFD drum brake installed.
