Claims

[Scope of utility model registration request]

A friction material pad of a caliper that presses against a disc plate with a pressing force corresponding to the hydraulic pressure in the oil chamber to stop the disc plate, and a piping route between the caliper and a master cylinder for brake operation. a hydraulic unit that adjusts the hydraulic pressure in the oil chamber to release the locked state of the brake; a wheel speed sensor that detects the number of rotations of the wheels and outputs a wheel speed signal; and a wheel speed sensor that detects the number of rotations of the wheels and outputs a wheel speed signal. and an electronic control device that determines the lock state of the brake by performing calculations based on the wheel speed and controls the hydraulic unit, and the friction material part is made of copper-based sintered alloy. An anti-lock braking device for motorcycles.
