a third position where the second rotor does not engage with the second brake pad, and

a fourth position where the second rotor engages with the second brake pad;

at least one brake caliper,

wherein the at least one brake caliper is configured to reposition the first brake pad between

a fifth position where the first brake pad does not engage with the first rotor, and

a sixth position where the first brake pad engages with the first rotor; and

a controller configured to:

control the first actuator to move the first rotor from the first position to the second position in response to a braking condition to brake a wheel,

control the second actuator to move the second rotor from the third position to the fourth position in response to the braking condition to brake the wheel, and

control the at least one brake caliper to move the first brake pad from the fifth position to the sixth position in response to the braking condition to brake the wheel.

9. The braking system of claim 8 , wherein the first actuator is configured to translate the first rotor between the first position and the second position.

10. The braking system of claim 9 , wherein the second actuator is configured to translate the second rotor between the third position and the fourth position.
