A hydraulic braking device includes an engaging base, a hydraulic brake, and a locking device. The hydraulic brake is provided on the engaging base. The locking device is adapted to fix the engaging base on a suspension fork of a bicycle, and includes a bolt and a handle, wherein the bolt passes through the engaging base to be screwed into a tapped hole of the suspension fork. The handle has a cam-shaped head pivotally connected to the bolt, and is pivotable between a first position and a second position. When the handle is located at the first position, the head presses against the engaging base to fix the engaging base on the suspension fork. When the handle is located at the second position, the engaging base is no longer being pressed against by the head, whereby the engaging base is movable relative to the suspension fork.

A V-type brake is provided for being assembled on a bicycle, the bicycle including two fork arms and a wheel set which is assembled between the two fork arms, the V-type brake including: two brake swing arms, respectively for being pivotably assembled on the two fork arms toward the wheel set, each said brake swing arm having a connecting portion; two brake pad assemblies, respectively assembled on the two brake swing arms, each said brake pad assembly having an assembling slot, the assembling slot positionably and slidably arranged within the connecting portion. A brake system is further provided, including the V-type brake mentioned above, further including a cable assembly, the cable assembly connected to the two brake swing arms, the cable assembly being operable to drive the two brake swing arms and the two brake pad assemblies to swing toward the wheel set.

A brake pad assembly for a bicycle includes a first brake pad, a second brake pad, and a spreader spring. The first brake pad has a first backing plate with a first rotor facing surface, and a first friction pad secured to the rotor facing surface. The second brake pad has a second backing plate with a second rotor facing surface, and a second friction pad secured to the second rotor facing surface and facing the first friction pad. The spreader spring has a first leaf that is fixed to the first brake pad and a second leaf that is fixed to the second brake pad. At least a portion of the first leaf is positioned between the first rotor facing surface and the first friction pad, and at least a portion of the second leaf is positioned between the second rotor facing surface and the second friction pad.

The spreader spring has a first leaf that is fixed to the first brake pad and a second leaf that is fixed to the second brake pad. At least a portion of the first leaf is positioned between the first rotor facing surface and the first friction pad, and at least a portion of the second leaf is positioned between the second rotor facing surface and the second friction pad.

A braking system includes a vehicle having a front brake and a rear brake. The system includes a moveable structure connected to a rear brake. The rear brake may be a hydraulic brake. When the rear brake is actuated, the moveable structure moves. The movement of the structure pressurizes hydraulic fluid in a tube which actuates a front hydraulic brake.

The present invention is directed towards a disk braking system for a bicycle having a rear disk coupled to a rear wheel. A rear brake caliper is coupled to a rear brake lever and the rear brake caliper is also coupled to a hydraulic actuator which has a piston that slides within a cylinder filled with hydraulic fluid and hydraulic tubing coupled to the cylinder and a front brake. When the rear wheel and rear disk are rotating, the rear brake caliper can be actuated which causes compresses rear brake caliper against the rear disk to slow the rotation of the rear wheel. The movement of the rear brake caliper can actuate the hydraulic actuator which causes hydraulic fluid to flow through the hydraulic tubing to actuate a front brake.

A banjo fitting is provided that may include an annular portion with an internal bore that extends along a first axis, and a hose attachment portion that extends radially from the annular portion, and has an internal fluid passageway extending along a second axis formed at an angle to the first axis. A seal rupturing structure may be positioned within the internal fluid passageway of the hose attachment portion.

A bicycle brake device comprises a friction member, a base member, and a piston. The base member includes a hydraulic cylinder. The piston is movable in the hydraulic cylinder in a movement direction so as to move the friction member toward a rotatable member. The piston is at least partially provided in a frame area defined by an outline of a bicycle frame when viewed from the movement direction in an attachment state where the base member is attached to the bicycle frame.
