Hydraulic Control Assembly - Antilock Brakes: Description and Operation
The hydraulic unit replaces the conventional master cylinder and vacuum-operated servo. This unit is comprised of a master cylinder, hydraulic servo
cylinder, brake fluid reservoir, independent pump for hydraulic pressure and a valve block which modulates pressure to the individual calipers. The valve
block contains six solenoid valves, three inlet and three outlet, this gives each brake circuit one inlet and one outlet valve.
If the ABS system should become inoperative for any reason, all the solenoid valves will be de-energized and the brake system will operate in the
same way as a conventional braking system.
