A disc brake rotor apparatus includes an annular inner member for mounting to a hub, an annular outer member concentric with the annular inner member and having opposite braking surfaces, a first intermediate member extending radially outwardly from the annular inner member to the annular outer member, and a second intermediate member extending radially outwardly from the annular inner member to the annular outer member. The first intermediate member is at least partially and axially spaced apart from the second intermediate member and forms a chamber therebetween.

A brake lining of a disc brake device is disclosed, wherein the brake lining includes a carrier and a friction block. The carrier has a bearing portion, which has the friction block provided thereon, and a guide portion connected to an end of the bearing portion. A first virtual line passes through a free end of the guide portion and a junction between the guide portion and the bearing portion, and a second virtual line passes through two opposite points of the disc periphery, wherein an included angle formed therebetween is greater than 0. The smallest possible included angle in any embodiments is formed if the first virtual line passes through an end corner of the friction block. With such design, the disc would not be hindered by nor collide with the friction block during installation, which reduces the difficulty and time for installing or fixing the disc brake device.

A braking system is proposed for a vehicle, in particular a lightweight vehicle, in particular a pedal cycle, comprising a brake device, a mechanical urging device, and a hydraulic urging device, wherein the mechanical urging device and the brake device form a parking brake device, and the hydraulic urging device takes the form of a hydraulically actuable release device for the parking brake device.

A disk brake device has a fixing member, a housing, two brake pads, a driving assembly, and a pushing element. The driving assembly is mounted on the housing and has an axle, a driving arm, a driving disk, a pushing disk, multiple driving elements, and a spring. The driving disk is mounted securely on and around the axle. The pushing disk is mounted rotatably on and around the axle. Each of the driving disk and the pushing disk has a side facing each other and multiple guiding recesses defined in the side. Each guiding recess has a deep end and a shallow end. The driving elements are held respectively in corresponding guiding recesses. The pushing element is mounted between the driving assembly and the fixing member and abutting against one of the driving assembly and the fixing member.

A hydraulically operated disc brake caliper group with a fixing side faced towards a load-bearing element when mounted on it. The fixing side is configured to substantially rest directly on the load-bearing element, and a hydraulic connector is positioned at the fixing side of the caliper body.

This configuration makes it possible to house the tube entirely in the load-bearing element of the bicycle, and to have complete closure of the opening on the load-bearing element. Furthermore, if vibrations generated while the bicycle is in motion loosen the fasteners, they can be retightened without having to dismount the caliper group.

A hydraulic braking system connector comprises a first coupling terminal having an annular abutment surface, a coupling sleeve having a first axially outer annular portion, receiving the first coupling terminal, an annular wall with a first annular abutment surface to abut the first coupling terminal abutment, and a second axially outer annular portion, to be coupled with a component of the hydraulic braking system. A first annular locking element is axially moveable between a rest position and a locking position. A first annular hydraulic sealing element is configured to be activated by the first annular locking element when in the locking position. The annular abutment surface of the first coupling terminal is in abutment on the first annular abutment surface of the coupling sleeve when the first annular locking element is in the rest position.

An ABS modulator support structure of a saddle type vehicle includes a main frame, a down frame, a pair of shroud which cover the right and left side of the frames, a radiator, a reserve tank which stores a coolant for the radiator, and an ABS module. The radiator is arranged on one (left side) side of the down frame 18 in a width direction of the vehicle. The ABS module is arranged on the other (right side) of the sides of the down frame in the width direction of the vehicle. The reserve tank and the shrouds are arranged outside the ABS module.

A foot brake structure for a mobility device includes: a footboard having an upper surface extending in a plane direction and having a rear wheel at a rear thereof; and a friction plate positioned above the rear wheel, having a portion extending forward of the rear wheel and rotatably assembled to a rear end of the footboard by a rotating shaft, and having a lower surface brought into contact with or spaced apart from a surface of the rear wheel depending on whether or not the friction plate is rotated around the rotating shaft, wherein when the friction plate is rotated around the rotating shaft by an external force, the lower surface of the friction plate is brought into contact with the surface of the rear wheel, thereby applying a braking force to the rear wheel.

A control device is provided for controlling a human-powered vehicle. The control device includes an electronic controller. The human-powered vehicle includes a drive unit, a brake device, and a brake control device. The drive unit is provided with an electric motor that assists in propulsion of the human-powered vehicle. The brake device generates brake force. The brake control device controls the brake force with an electric actuator differing from the electric motor. The electronic controller is configured to control the electric motor in accordance with an actuation state of the brake control device.

A human-powered vehicle component includes an input device, to which first information related to at least one of a human-powered vehicle, a rider of the human-powered vehicle, and environment of the human-powered vehicle is input. The human-powered vehicle component further comprises an electric actuator and an artificial intelligence processor configured to generate second information for controlling the electric actuator in accordance with the first information input to the input device.
