  "textContent": "This brake force amplifier comprising a piston (6) actuated by a pressure differential between two chambers, a plunger (11) mounted axially displaceable within this piston (6) between positions controlling the evolution of this pressure differential by means of switching means (16,17,18), a thrust assembly (26,27) connected to the master cylinder of the corresponding brakes, and a reaction disc (13) interposed between the piston (6) and the plunger (11) on one hand, and the thrust assembly (26,27) on the other hand, the plunger (11) displacing axially under the combined actions of the brake pedal control (9) and the reaction disc (13). In the junction region between the thrust assembly (26,27) and the reaction disc (13), at least one cavity (28) is provided for absorbing deformations of the reaction disc (13) during its compression between the piston (6) and the thrust assembly (26,27).",
