Hydraulic Control Unit Decay Solenoids

HYDRAULIC CONTROL UNIT DECAY SOLENOIDS
There are 4 decay solenoids, one for each wheel. In the released position they provide a fluid path from the Master Cylinder to the wheel brakes of the vehicle. In the actuated (decay) position, they provide a fluid path from wheel brakes of the vehicle to the sumps. The Decay Solenoids are spring loaded in the released (build) position during normal braking.
