A brake device for a vehicle includes a brake pedal rotatably supported on a support shaft and extending in a front ward direction from the support shaft in the longitudinal direction of the vehicle. A master cylinder is located on the rear side of the support shaft in the longitudinal direction of the vehicle for generating a braking hydraulic pressure according to the rotational operation of the brake pedal. An operational amount detector is mechanically connected to the brake pedal for detecting the rotational amount of the brake pedal. The master cylinder includes an axis that is arranged vertically and is located above the support shaft with the operational amount detector being located on the rear side of the support shaft in the longitudinal direction of the motorcycle. Thus, the master cylinder and the operational amount detector can be densely arranged in the longitudinal direction of the vehicle.

Bicycle disc brake

In a braking system for a motorcycle, a brake includes a plurality of applicators which are respectively operated by hydraulic braking pressures fed from first and second actuators, and a common antilock modulator is provided for controlling and reducing the hydraulic braking pressures from the first and second actuators. This makes the braking system having antilock control function simplified in structure.

Braking system for motorcycle

A hydraulic brake system includes: a hydraulic pressure source provided for a vehicle, and including a hydraulic-pressure generating device and a reservoir; a plurality of hydraulic brakes provided for respective wheels of the vehicle, and configured to restrain rotations of the respective wheels; and a control valve device including at least one hydraulic-pressure control valve group disposed between the hydraulic-pressure generating device and at least one of brake cylinders of the hydraulic brakes and/or between the reservoir and the at least one of the brake cylinders. Each of the at least one hydraulic-pressure control valve group includes (a) at least one ON/OFF control valve and (b) at least one linear control valve that are disposed in parallel with each other.

Hydraulic brake system

A primary brake system operated by either one of a hand operated means and a foot operated system is mounted on one of the front and rear wheels, and a secondary brake system operated in response to the operation of the primary brake system is mounted on the other wheel. Consequently, it is possible to provide a braking-force distribution for the front and rear wheels with a predetermined common characteristic, leading to an improved brake feel. A braking-force control is provided for controlling the braking-force distribution to the front and rear wheels in accordance with the operating forces of a first input operated by the hand operated element and a second input operated by the foot operated element, so that an ideal distribution characteristic falls within a region between a first braking-force distribution characteristic for the front and rear wheels by the hand operated element and a second braking-force distribution characteristic for the wheels by the foot operated element, such region being a braking-force distribution characteristic region at a time when the hand and foot operated elements are operated simultaneously.

Braking system for motorcycle having apportioning control

A brake apparatus for motorcycles with a master cylinder connected directly to a front wheel brake cylinder and connected through pressure control valves to a rear wheel brake cylinder. An adjustment varies the ratios of application of pressures to front and rear brakes through variation in valve spring settings to accommodate variations in load. A sensing system may be employed to determine application of braking force to the front wheel. This system may take the form of a mechanical servo mounting the front brake calipers, a direct pressure application in the master cylinder or a transducer measuring brake pressure to the front wheel. When braking to the front wheel is sensed above a selected threshold, the ratio of brake pressure of the front to rear wheels is reduced. A orifice restriction associated with the pressure control valves reduces sensitivity to variation in braking due to valve action.

Motorcycle brake system having dual master cylinder proportioning

In a braking device of a motorcycle, in which a rear wheel braking mechanism is operated in conjunction with a front wheel braking operation, accurate determination of a reduction in rear wheel load is provided, and additional reduction of the rear-wheel load is prevented. Determination of a reduction in rear-wheel load is based on vehicle speed in the front wheel braking operation, hydraulic pressure of a brake caliper on the front wheel side, and respective slip ratios of the front and rear wheels. When the rear-wheel load is reducing, hydraulic pressure of a brake caliper on the rear wheel side is controlled so as to keep the slip ratio of the rear wheel at or below a set value. A hydraulic modulator supplies/evacuates the hydraulic pressure to/from the brake caliper on the rear wheel side, and the slip ratio of the rear wheel is controlled by electrically controlling the hydraulic modulator.

A disk brake system employing a caliper support bracket pivotally mounted about the axis of a first disk which is coupled with a hydraulic cylinder. The hydraulic cylinder in turn drives a second caliper assembly on a second disk. The hydraulic cylinder driven by the caliper support bracket is aligned with the plane of the disk. A bell crank may be employed in alignment with the disk to couple the caliper support bracket and the hydraulic cylinder together.
