Brake Fluid - GMC 2010 Acadia Owner's Manual

Notice: Continuing to drive with
worn-out brake pads could result
in costly brake repair.
Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in
the proper sequence to torque
specifications in Capacities and
Specifications on page 12 2.
Brake linings should always be
replaced as complete axle sets.
Brake Pedal Travel
See your dealer/retailer 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 that brake service might be
required.
Brake Adjustment
Every time the brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear.
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. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to
get new, approved replacement
parts. If this is not done, the
brakes might not work properly.
Vehicle Care
For example, installing disc brake
pads that are wrong for the vehicle,
can change the balance between
the front and rear brakes
worse. The braking performance
expected can change in many other
ways if the wrong replacement
brake parts are installed.
