BRAKE WARNING
SYSTEM
DESCRIPTION
The brake warning system consists
of warning lamp, hand brake switch
and a brake line pressure differential
warning switch. The whole circuit is
shown in Figure BE-55.
The brake warning lamp glows
when the hand brake is applied.
When the ignition switch is set to
"ON", current flows from the ignition
switch to the warning lamp. When the
hand brake is applied, hand brake
warning switch is closed and warning
lamp glows.
The brake line pressure differential
warning switch causes warning lamp to
glow when problem occurs in brake
lines. For information on brake line
