As the motor rotates, it drives the pluger – type ABS pump and raises the brake fluid pressure to approximately 25,000 kPa, 250 bar, 3,600 lb/in². The eccentric bearing is attached to the motor shaft end; it contains the pump plunger.
When the plunger is pushed, the brake fluid in the plunger chamber is pressurised and fed to the accumulator, solenoid and pistons, via the check valve. When the pressure in the accumulator exceeds 35,000 kPa, 350 bar, 5,000 lb/in², the relief valve opens to release the excess pressure to the reservoir.
