A hydraulic brake device for a vehicle includes an auxiliary piston having an effective cross-sectional area larger than that of a master piston, and a pressure transmitting chamber provided between the large diameter portion and the master piston. A sensor element of the combined pressure and temperature sensor includes a through-hole to a diaphragm and a bore for accommodating a temperature sensor. A load translation device generally includes an actuator, a ground drilling device coupled to and moveable with a portion of the actuator, and a frame coupled to and moveable with another portion of the actuator. The metal foil includes a pressure absorption portion and a hard portion adjacent to the pressure absorption portion. The block copolymers can be based upon acrylic monomers, and some possess adhesive properties. The non-compensation signal points and the compensation signal points are point-symmetry.
