During Operation
1. Reduction of the brake fluid pressure for the rear brakes
If the signal for reductron of the brake fluid @%sur$; is I!!
output from the control unrt, the electrrc current will flow to
the release solenord valve, the release plunger will move to
pi
1
the left, release valve seati will open, and, simul%neousJy,
m7
release valve seat B will close. Air will flow hto chamber B _
through the art- filter, to the air Intake port,
and io
release i-y
valve seat A. When chamber B reaches atmospheric ~-
pressure, the pressure drtference between chamber A G
(vacuum condition) and chamber B will cause the vacuum
piston to move to the left, compressing the main spring. ~*
The brake fluid pressure plunger will move t0 the left I
simultaneously with the vacuum piston and close the ch.eck ._=
valve. Whenthe check valve IS closed, the flow of brake z
fluid from the master -cylinder to the rear brakes is 1
disrupted, and, at the same time, the brake fluid pressure is?
decreased b.ecause of the. increase in the capacity of brake '
fluid rn chamber C. _ _
