A brake assembly (22, 30) for a stroller has a wheel (20) rotatable about a wheels axis (A) and a plurality of pockets (50) on the wheel spaced from and circumferentially around the wheel axis. A brake lever (76) has an actuator arm (78) and a link arm (80) fixedly connected to one another and is movable between a braking orientation and a released orientation. A boss (108) is driven by the link arm between a braking position and a released position corresponding respectively to the braking and released orientations of the brake lever. A biasing mechanism is configured to bias and retain the boss (108) into engagement with one of the plurality of pockets (50) when the brake lever (76) is moved to the braking orientation and to bias and retain the boss out of engagement with the plurality of pockets when the brake lever is moved to the released position.
