Brake assemblies, and scooters and skateboards incorporating the same. The brake assemblies include an actuator that is positioned rearward of the body of the scooter or skateboard and includes a brake member that is selectively pivoted or otherwise moved into braking contact with a rear wheel assembly responsive to rider-applied braking inputs to the actuator. In some embodiments, the rear wheel assembly includes a truck with a chassis that is pivotally coupled to the body and to which the rear wheels are rotatably mounted. In some embodiments, the brake member is adapted to apply braking forces to a ground-contacting surface of at least one of the rear wheels responsive to braking inputs applied by a rider to the actuator. In some embodiments, the brake assembly is configured to maintain its orientation relative to the rear wheel regardless of the pivotal orientation of the body relative to the chassis.
