Bleeding
hydraulic

system

Bleeding
the

hydraulic
brake

system
deserves

much

attention
as
it
is

an
essential

factor
for

regular
service

brake

operation

As
a
matter
of

fact

during
the

brake
service
air
is

likely
to

creep
into
the
circuit
with

the
result
that

the

fluid
action
is

altered
and
the
brake

pedal
becomes

spongy

at
the
travel
end

Bleeding
should
be
carried
out
at
first
with

the
masler

cylinder
then
from
the

longest
line
from
the

master

cylinder
and
then
finish
