Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a brake device that can miniaturize a wheel cylinder.SOLUTION: A strain sensor 37 is set up in an installation member 23 for constituting a disk brake 21. The strain sensor 37 detects predetermined vibration (Goo sound) caused by slipping-down of a vehicle based on a change in strain of the installation member 23. When operating a parking brake, a parking brake controller 38 supplies an applying current A larger than an initial current value Ao up to eliminating the predetermined vibration when detecting the predetermined vibration by the strain sensor 37 after supplying the initial current value Ao for imparting minimum pressing force that can stop the vehicle to an electric motor 32. |
