VSA Mode (Pressure Intensifying Operation)

In pressure intensifying operation, the apply valve opens, the dump valve closes, and pump motor operates. The cutting valve is closed by the brake fluid for VSA control pressing on the pressure piston. At the same time, the brake fluid in the pressure chamber provides pressure to the brake caliper. See Fig 1 .
