れる。 In the above structure, when the driver performs a braking operation, the hydraulic oil supplied by the master cylinder is sent to the back surface of the first piston 7 via the direct-acting circuit 22 and the guide hole 18 of the first cylinder 5. Due to the movement of the first piston 7, the brake element 12 is moved to the brake disc 2.
The water film and water droplets on the surface of the brake disc 2 are completely wiped away, and the brake disc 2 is heated by the frictional heat between the brake disc 2 and the brake disc 2, causing an instantaneous drying phenomenon on the surface. Accompanying braking is performed.

れる。 When the pushing operation of the first piston 7 is finished,
The working oil pressure in the direct acting circuit 22 reaches the upper limit of the pressure of the hydraulic system, and this pressure similarly acts on the interlocking circuit 23, causing the relief valve 2 to close.
Move the valve of No. 4 to connect the interlocking circuit 23,
Hydraulic oil is supplied to the interlocking circuit 23. This hydraulic oil acts on the back surface of the second piston 8 to push out the second piston and move the brake element 13 to the brake disc 2.
Braking is applied to the brake disc by pressing it against the surface of the brake disc.

由状態に復帰される。 When the brake is released, when the hydraulic pressure of the master cylinder decreases due to shutting off of the hydraulic pressure source, the hydraulic oil in the first cylinder 5 is transferred to the direct drive circuit 22, and the hydraulic oil in the second cylinder 6 is transferred to the check valve 25. The water is then returned to the hydraulic system via the interlocking circuit 23, and each brake element 12, 13 is returned to its free state.

うる実用上の優れた効果をもつものである。 Since the present invention has the above-mentioned configuration, the braking operation when driving in the rain is performed by first wiping away the water film on the brake disc surface with the first caliper to remove the cause of slippage, applying advance braking, and then applying the first brake using the delay means. By operating the two calipers at different times and using the first and second calipers to perform effective braking, the vehicle performs the same function as on a clear day, so there is no need to worry too much about braking interference caused by rainwater. In addition to eliminating the burden of attention and providing a comfortable driving feeling, this system has excellent practical effects as it has a simple structure, long durability, and can be easily mass-produced.
