Hydraulic Control Assembly - Antilock Brakes: Description and Operation

Hydraulic Modulator

The hydraulic modulator receives and processes the signals from the control unit. It helps to constantly maintain the correct pressure in the wheel
cylinders. In the event of a wheel lock, pressure in the locked wheel cylinder is lowered and the integral electrical regulator pump pumps brake fluid
from the wheel cylinder back to the master cylinder.
