Brake Pedal Travel; Brake Adjustment; Replacing Brake System Parts - Chevrolet 2005 T-Series Owner's Manual

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.

Brake Adjustment

Every time you make a brake stop, your brakes adjust
for wear.
Four-Wheel Disc Brakes
(Hydraulic Only)
Your vehicle has four-wheel disc brakes.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Brake linings should always be replaced as complete
axle sets.

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-quality GM
brake parts. When you replace parts of your braking
5-36
system — for example, when your brake linings wear
down and you need new ones put in — be sure you get
new approved GM replacement parts. If you do not,
your brakes may no longer work properly. For example,
if someone puts in brake linings that are wrong for
your vehicle, the balance between your front and rear
brakes can change — for the worse. The braking
performance you have come to expect can change in
many other ways if someone puts in the wrong
replacement brake parts.
Air Brake Systems
If your vehicle has air brakes, it is important to get rid of
moisture in your system. Moisture will damage your
system if it is not removed daily.
There are two ways to do this. One is automatic if your
air-brake vehicle has the optional moisture ejector. If
your vehicle does not have that option, you must drain
the air reservoirs every day.
Drain them at full system pressure. To be sure you
are at full pressure, check your air pressure gage. It
should read at least 100 psi (692 kPa).
Moisture Ejector
If you have air brakes with a moisture ejector, the valve
automatically ejects moisture from the purge tank
when the air compressor cycles.
