A brake system for a vehicle such as a bicycle is disclosed. The brake system may comprise an improved master cylinder assembly configured for adjustment (such as adjustment of the stroke length, stroke start, etc.). The brake system may comprise a caliper assembly with an improved arrangement of flow paths configured to facilitate maintenance (such as to remove/bleed air and/or fluid from the body of the caliper assembly, inspection, etc.); the caliper assembly may also be configured for use with a tool (e.g. configured to fit in body to remove/bleed air and/or fluid from flow paths during maintenance). The master cylinder assembly may be configured (e.g. manufactured/produced, assembled, etc.) so that a setting and/or adjustment of the brake stroke and/or lever action/actuation can be provided by any one independent mechanism or one separate adjustment mechanism (e.g. without any other adjustment mechanism) or by a combination of adjustment mechanisms (e.g. in a combination with one or more adjustment mechanism); operation of a mechanism for setting and/or adjusting the brake stroke (e.g. travel of piston) may comprise engagement of a pushrod; the mechanism may comprise a feature configured to engage the pushrod (e.g. by direct action on the pushrod or a feature of the pushrod or by indirect action through a link, adjuster, etc. configured to engage the pushrod). The master cylinder assembly may be configured to be set and/or adjusted/tuned within the indicated range to provide an intended performance and/or “feel” for the operator at the brake lever (e.g. at an adjuster, link, etc.).

An adapter body is configured to be attached to a vehicle body in each of a first orientation in which a caliper body is coupled to the vehicle body via the adapter body in a first position corresponding to a first disc brake rotor having a first outer diameter, and a second orientation in which the caliper body is coupled to the vehicle body via the adapter body in a second position corresponding to a second disc brake rotor having a second outer diameter different from the first outer diameter. The indicator is configured to indicate an correspondence between an orientation of the adapter body and at least one of the first disc brake rotor and the second disc brake rotor.

A cycle braking system is provided where the system comprises a brake sphere engaged with a shaft adjacent to a wheel of a cycle and a brake caliper, where the brake caliper is mounted to a cycle's chassis and aligned around the brake sphere rotor. In one embodiment, the cycle braking system further comprises brake pad(s) with an inner side and a contact side, a brake housing having the brake pad(s) positioned between the caliper and the contact side facing the brake sphere; and the brake caliper connected to a cycle's hydraulic lines.

A linear brake for a bicycle comprises a pair of pivot mounts, each of which is mounted on a bicycle member laterally of a wheel rim, one on either side of the wheel. A brake arm is pivotally mounted in levered relation on each pivot mount below adjacent and biased away from the wheel rim. A brake shoe is affixed to each brake arm upper end. A control cable is affixed to a control member above the wheel with the control member being connected to the center of a yoke cable. The yoke cable is affixed to the lower end of each brake arm with yoke cable passed partway around the annular component on each pivot mount.

The disclosure provides a bicycle caliper including a casing assembly and a plurality of pistons. The casing assembly has a first fluid inlet, a second fluid inlet, a first fluid channel, a plurality of piston chambers, and a second fluid channel. The first fluid channel has a first connection opening and a second connection opening opposite to each other. The first connection opening and the second connection opening of the first fluid channel are respectively in fluid communication with the first fluid inlet and the second fluid inlet. The first fluid channel penetrates through the piston chambers. Two opposite openings of the second fluid channel are respectively in fluid communication with the first connection opening and the second connection opening of the first fluid channel, and the second fluid channel does not penetrate through the piston chambers. The pistons are respectively and movably disposed in the piston chambers.

A personal mobility vehicle, such as a scooter, includes at least one battery and motor for powering at least one driven wheel. The vehicle also includes a braking assembly configured to isolate the motor from the at least one driven wheel such that power is terminated from the motor to the at least one wheel in response to a user engaging a braking assembly of the vehicle. The vehicle can include a switch or position sensor that interacts with the braking assembly to initiate the isolation of the motor from the at least one driven wheel and the switch or position sensor preferably is inaccessible to the foot of the user.

A bicycle wheel hub for mounting a brake disc in relation to a spoke-holding flange. The hub has a connection portion with a first annular sector that is axially external with respect to the spoke-holding flange and a second annular sector that is axially external with respect to the first annular sector. A circumferential groove axially arranged between the first and the second annular sectors.

Example brake systems and apparatus for providing pitch control on bicycles are described herein. An example rear brake caliper described herein includes a caliper housing to be coupled to the bicycle. The caliper housing includes a first port to be fluidly coupled to a first fluid line fluidly coupled to a front brake actuator and a second port to be fluidly coupled to a second fluid line fluidly coupled to a front brake caliper. The rear brake caliper also includes a valve between the first port and the second port. The valve is operable to affect fluid flow between the first port and the second port.
