ABSTRACT:
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.
