Hydraulic Assembly
Modulator Unit Schematic
Modulators for each wheel and solenoid valves are integrated in the modulator unit. The modulators for front and rear brakes are of independent
construction and are positioned vertically for improved maintainability. The modulators for rear brakes are provided with a proportioning control valve
function in order to prevent the rear wheels from locking when the anti-lock brake system is malfunctioning or the anti-lock brake system is not
activated. The inlet and outlet valves are integrated in the solenoid valve unit. There are three solenoid valves, one for each front wheel, and one for both
rear wheels.
