Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together
if the vehicle is to have really good braking. Your
vehicle was designed and tested with top
brake parts. When you replace parts of your braking

Air Brake Systems (If Equipped)
If you have air brakes, it is important to get rid of
moisture in the system. Moisture will damage your
system if it isn't removed daily.
Drain them at full system pressure. To be sure you're at
full pressure, check your air pressure gage. It should
read at least 100 psi (692 kPa).
Moisture Ejector (If Equipped)
If you have air brakes with a moisture ejector, the valve
automatically ejects moisture from the reserve tank
when the air compressor cycles.
There are two ways to do
this. One is automatic if

your air
brake is equipped
with the moisture ejector. If
your vehicle doesn't have
that option, however, you
must drain the air reservoirs
every day.
