OPERATOR'S MANUAL

USING THE BRAKE SYSTEM STARTING AND OPERATING THE VEHICLE
– 124 – Y53-6027
Medium Duty (R05/09)
If the buzzer sounds while driving, or if the BRAKE light
comes on, do the following:
1. Slow down carefully.
Here are some things you can do to assist in slowing
the vehicle:
• Downshift - Putting the transmission into a lower
gear will help slow the vehicle.
• Pump the brakes - Pumping the brake pedal may
generate enough hydraulic pressure to stop the
vehicle.
• Use the parking brake - The parking or emergency
brake is separate from the hydraulic system. There-
fore it can be used to slow the vehicle.
2. Move a safe distance off the road and stop.
3. Set the parking brake. (See page 106
.)
4. Turn on the emergency flasher and use other warning
devices to alert other motorists.
Wet or Overheated Brakes
• Wet Brakes
If you have been driving in heavy rain or deep stand-
ing water, your brakes will get wet. Water in the brakes
can cause them to be weak, to apply unevenly, or to
grab. These conditions can cause a lack of braking
power, wheel lockups, or pulling of the vehicle to one
side or the other.
Avoid driving through deep puddles or flowing water if
possible. If not possible, you should to the following:
• Slow down.
• Place transmission in lower gear.
• Gently press on the brake pedal.
• Increase engine speed while keeping light pressure
on the brake pedal for a short distance to dry out the
brake linings.
• Overheated Brakes
