See your service outlet if normal pedal travel
is not restored, or if there is a rapid increase
in pedal travel, which could be a sign of other
brake trouble.
NOTE :
"Riding The Brake" by resting your foot
on the brake pedal when not intending to brake
can cause abnormally high brake temperatures,
excessive lining wear and possible damage to
brakes .
REMINDER : The front disc brakes have a
built-in wear indicator that is designed
to make a warning noise when the lin-
ings are worn to where replacement is
required .
For further information
on
brake system maintenance refer to the
SERVICE AND MAINTENANCE section.
PARKING BRAKE
To set parking brake, pull up the handle
located on the floor against the left wall, be-
low the instrument panel.
For maximum holding power, depress regular
brake pedal at the same time .
To release parking brake push the handle
down.
As a reminder, the optional "PARK BRAKE"
reminder light is designed to glow whenever
the parking brake control is not fully released,
and the ignition is on.
Never drive vehicle with parking brake set
as this may overheat or otherwise damage
rear brakes .
The amount of force required to apply park-
ing brake can be adjusted by turning a tension
adjustment knob located at the upper end of
the lever. This also adjusts the degree of brake
application. The greater the force required at
the lever the greater the degree of brake appli-
cation .
NOTE :
The parking brake should be set first
whenever the driver's seat is left unattended .
If the vehicle is parked on a grade and the
transmission is placed in "PARK" before the
parking brake is set, the weight of the Motor
Home may exert so much force on the parking
pawl in the transmission than the transmission
selector lever cannot later be pulled out of
"PARK." To prevent this, the parking brake
should be applied BEFORE moving the trans-

mission selector lever to "PARK." When prepar-
ing to move the vehicle, the shift indicator
should be moved out of the "PARK" position
BEFORE releasing the parking brake. It is good
driving practice to set the parking brake first,
and release the transmission from "PARK" first
at all times, even on the level. If "torque lock",
as this condition is called, does occur, it may be
necessary to have another vehicle nudge this
vehicle up hill, to take some of the pressure off
the transmission while the driver pulls on the
transmission selector lever.
HEADLIGHT DIMMER SWITCH
To obtain high or low beam headlights, push
the foot dimmer switch located on the floor to
the left of the brake pedal. Each time the switch
is depressed, the light beam changes. A headlamp
beam indicator, on the face of the speedometer,
is designed to light up when the headlights are
on high beam.
HEADLIGHT "FLICKER"
The headlight circuits are protected by a
circuit breaker in the light switch . An overload
on the breaker will cause the lights to "flicker"
on and off, or in some cases to remain off. If
this condition develops, have your headlight
electrical circuit checked immediately.
