Title: DISC BRAKE DEVICE
Abstract:
Provided is a disk brake device, which can retain proper braking responsibility from a low-deceleration range to a high-deceleration range and which can improve a brake feeling in the low-deceleration range. At a braking time in the low-deceleration range of a low brake liquid pressure, a brake liquid absorbing mechanism (9) absorbs the brake liquid to be fed to a caliper cylinder, so that the quantity of a brake liquid to be consumed increases. As a result, the depression stroke of the brake pedal becomes longer as the quantity of the consumed brake liquid becomes larger, so that the brake pedal feeling in the low-deceleration range improves. At a braking time in the high-deceleration range of the low brake liquid pressure, on the other hand, the brake liquid absorbing mechanism (9) does not absorb the brake liquid, so that the quantity of the consumed brake liquid increases. As a result, the depression stroke of the brake pedal decreases so that the proper braking responsibility is retained at the braking time in the high-deceleration range.
