A parking brake assembly includes a disc defining an aperture and a ramp located proximate the aperture; a pedal configured to rotate the disc in a locking direction or an unlocking direction; and an actuator including a body and a spring biased to urge the body toward the aperture, the actuator further including a pin positioned and arranged to travel along the ramp when the disc is rotated relative to the actuator, where the pin is displaced along the ramp when the disc is rotated in the locking direction. The spring is allowed to push the body through the aperture and into a mating hole of the wheel or associated with the wheel such that the pin travels downward along the ramp, and wherein, when the disc is rotated in the unlocking direction, the spring is prevented from pushing the body through the aperture and into the mating hole such that the pin travels upward along the ramp.
