A braking system includes brake circuits and a brake stability module. The brake circuits are configured to be independently activated and deactivated and when activated apply braking force at respective wheels of a vehicle. The braking stability module is configured to i) detect a failure with a first one of the brake circuits of a first axle of the vehicle, ii) lock or adjust an amount of engagement of a differential of the first axle of the vehicle to distribute brake force from a second one of the brake circuits of the first axle to one of the wheels at the first one of the brake circuits, and iii) control operation of the second one of the brake circuits to brake torque the one of the wheels at the first one of the brake circuits.

Brake torque transferring via limited slip and locking differentials based on detected failure of brake circuits

A brake actuator control system for a vehicle includes: a maximum load module configured to determine maximum clamping loads of brake actuators, respectively, of the vehicle, the brake actuators configured to, independently of each other, slow rotation of wheels, respectively, of the vehicle; a limit module configured to set a load limit to a minimum one of the maximum clamping loads of the brake actuators; a target load module configured to limit a target load for the brake actuators to less than or equal to the load limit; and a power control module configured to apply power to electric motors of the brake actuators, respectively, based on the target load.
