Abstract: 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.

Abstract: An auxiliary device for a hydraulic brake assembly used on a two-wheel vehicle includes a body and a transmission device. The body has four cylinders respectively connected to the left and right brake lever hoses, and front and rear wheel brake hoses. By the operation of the transmission device, the front and the rear wheels are braked by either pulling the left brake lever or the right brake lever. The front wheel brake unit and the rear wheel brake unit are simultaneously activated by pulling either the left brake lever or the right break lever. The front wheel is braked right after the rear wheel is braked, and the braking force applied to the rear wheel is larger than that to the front wheel.
