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

The
Master
