A brake-aiding device includes a casing and a drive mechanism installed in the casing. The drive mechanism has a revolving axle, and first revolver, a second revolver and a driven revolver that rotate against the revolving axle. The driven revolver has at least one propping portion for providing unidirectional stop to the first revolver and the second revolver. When brake lever cables of a two-wheeled vehicle are connected to the first and second revolver, and front- and rear-wheel brake cables of the vehicle are connected to the driven revolver, by operating either of the vehicle's left and right brake levers, both of the vehicle's front and rear wheels are braked. During the braking, the rear wheel is brakes before the front wheel is brakes, and a braking force at the rear wheel keeps greater than a braking force at the front wheel braking force. |
