An adjustment structure of a hydraulic brake system is provided, which includes a main body, a piston and an adjusting device. The main body includes at least one fluid reservoir, an inner chamber and at least one fluid passage. The inner chamber includes a cylinder channel and an opening part, and the cylinder channel is communicated with the fluid reservoir by at least one fluid port. The piston is driven by the brake cable to be limitedly moved in the cylinder channel. The piston includes a cable hole for receiving the brake cable, and the piston has a normal operated position relative to the fluid port. The adjusting device is disposed in the opening part and is abutted against the piston. The adjusting device is operated to be moved relative to the brake cable such that the piston is adjusted to be returned to the normal operated position.

Adjustment structure of hydraulic brake system

A hydraulic disc brake device includes a cover, a hydraulic unit, an oil tube and a disc brake unit. The cover includes at least one accommodating space, at least one oil route, a proximal end and a distal end. The distal end towards a moving direction of the bicycle. The hydraulic unit includes a hydraulic cylinder and a piston. The hydraulic cylinder is assembled in the accommodating space. The piston is assembled in the hydraulic cylinder for controlling a pressure of the oil route. The disc brake unit is connected with the oil tube and controlled by a pressure of the oil tube.

Hydraulic disc brake device for a bicycle

The bicycle wheel includes a rim, a hub, a driving device, a plurality of first side pulling spokes, a plurality of first side pushing spokes, and a plurality of second side spokes. The rim has a first side and a second side. The hub is located in a center of the rim. The driving device is connected to the hub which is located on the first side of the rim. Each of the first side pulling spokes and the first side pushing spokes is connected to the rim and the hub, and located on the first side of the rim, respectively. Each of the second side spokes is connected to the rim and the hub, and located on the second side of the rim.
