Abstract

An apparatus and a system include an actuator assembly configured for controlling a movement of a manual mechanical linkage shaft in a manual brake system for a vehicle wheel. An electric motor drives the actuator assembly wherein a manually applied force to the manual mechanical linkage shaft is modulated or pulsed. A lock and release assembly is configured for engaging and disengaging the actuator assembly to and from the manual mechanical linkage shaft. Means actuates the lock and release assembly to engage the actuator assembly to the manual mechanical linkage shaft, and disengage the actuator assembly from the manual mechanical linkage shaft. An electronic controller controls the electric motor during a braking of the vehicle wheel to mitigate skidding of the vehicle wheel during the braking

Claims
