MASTER
VAC
DESCRIPTION
A
vacuum
suspended
Master
Vac
is
installed
behind
the
master
cylinder
As
the
brake
pedal
is
depressed
fluid
is
forced
under
high
pressure
through
the
brake
pipes
to
the
wheel
cylinders
to
retard
or
stop
the
vehicle
The
Master
Vac
contains
a
spring
loaded
diaphragm
of
IS2
4
mm
6
in
in
diameter
It
operates
on
negative
pressure
produced
n
the
engine
intake
manifold
The
tandem
master
cylinder
is
capable
of
producing
high
pressure
even
if
the
Master
Vac
is
faulty

Note
The
Master
Vac
diaphragm
