Abstract: Responsive to a hydraulic piston advancing out of a piston housing in a second brake arm and contacting a piston cam surface of a first brake arm, the second brake arm pivots around a second pivot. As this is happening, a cam surface in the second brake arm lifts a contact surface of a first force transfer member of the first brake arm, imparting torque to the first brake arm which then pivots around a first pivot. The cam surface is shaped to impart synchronous motion to the first and second pad holders. Splitting one of the brake arms with a centering member permits a centering adjust feature.

Abstract: Provided is a brake distribution structure including a first sliding block, a second sliding block, and a tube. The first sliding block connects to a rear brake line of a bicycle. The second sliding block connects to a front brake line of the bicycle. The first sliding block moves to brake a rear wheel of the bicycle, and then the first sliding block drives the second sliding block to move and thereby brake the front wheel of the bicycle. The brake distribution structure ensures that the rear wheel is always braked first, prevents brake lockup, reduces hazards otherwise arising from manmade false action, and maximizes rider safety.

Abstract: A hydraulic brake device includes a main body, a brake lever, a hydraulic rod, a connecting rod, a sleeve member and an elastic member. The elastic member has an assembling portion, a driving portion and a deformation portion. When a user actuates the brake lever suddenly and forcefully, the driving portion of the elastic member moves toward the hydraulic room; a pressure of hydraulic oil pushes the driving portion so as to indirectly force the deformation portion to deform and bend, so that the deformation portion and the driving portion slightly move toward the assembling portion; thereby, a volume of hydraulic oil is smoothly pushed into a brake caliper through a hydraulic pipeline, such that the user brakes a bicycle stably, smoothly and safely.

Abstract: A sequential brake control device for a cycle has a sliding connector and a front delaying and anti-lock spring set to serve to sequentially actuate a brake. A left lever cable and a right lever cable are commonly connected to the sliding connector. A front brake cable passes through the sliding connector and the front delaying and anti-lock spring set and is mounted in a front brake cable block abutting against the front delaying and anti-lock spring set. A rear brake cable may alternatively pass through the sliding connector and a rear suspension spring and is mounted in a rear brake cable block abutting against the rear suspension spring. When one or both brake levers are squeezed, a rear wheel is stopped before the front wheel does. The front and rear wheels are slowed down in speed first when a brake is applied and fully stopped at a lower speed of the cycle.
