  "textContent": "A braking pressure control apparatus including a first pressure source (31) including a power-operated pressurizing device (12), a second pressure source (14) operable by a manually operable brake operating member (10) to pressurize a fluid to a pressure higher than a level corresponding to the operating force of the brake operating member, a switching device (30, 152, 162) for selectively placing the braking system in a first state in which a brake cylinder (20, 28) is operated with the fluid pressurized by the first pressure source and a second state in which the brake cylinder is operated with the fluid pressurized by the second pressure source, and a change restricting device (32) operable upon a switching between the first and second states, to restrict a change of the operating state of the brake operating member and a change of the brake cylinder pressure, which change take place due to the switching, or a switching control device (32, S1-S4, S55-S60, S71, S72, S81, S82) for controlling the switching device based on running condition of a vehicle whose wheel is braked by the braking pressure.",
