A rollator brake having a combined service and parking brake, which brake comprises a pivoting brake handle (4) arranged at one end of a handled upright (2) and operatively connected with a braking device (6), which brake handle (4), when the same is raised toward the handle, is adapted to engage a service-brake position and, when the same is pushed downward away from the handle, is adapted to engage a parking-brake position. A gear rim (8) is arranged at either the hub of a braked wheel (5) or a shaft fixedly connected with the braked wheel, and a braking member of the braking device (6) is spring-biasedly arranged toward the parking-brake position in such a way that, in the parking-brake position, the braking member is adapted to penetrate between the teeth of the gear rim (8) for locking of the wheel (5), and that, in the service-brake position, the braking member is adapted to abut against the inside a rim of the wheel (5) for braking the same.
