A braking assembly for inhibiting rotation of a wheel around a rotation axis is provided. The braking assembly includes a drive gear, an actuator, an electric braking assembly, a mechanical braking assembly including a brake pad, and a brake rotor fixedly coupled to the wheel. The drive gear rotates with the wheel and includes a pinion. The electric braking assembly includes a coil surrounding the rotation axis, and a magnetic disc assembly concentric with the coil and configured to rotate relative to the coil. The magnetic disc assembly includes a plurality of magnets at a perimeter of the disc. The actuator engages the pinion to inhibit rotation of the magnets and generate an electro motive force to inhibit rotation of the wheel. The actuator engages the brake pad to contact the rotor and inhibit rotation between the wheel and the brake pad.
