Vehicle Care 203
Caution
Continuing to drive with worn-out brake
linings could result in costly brake repairs.
Some driving conditions or climates can
c
ause abrake squeal when the brakes are
first applied, clearing up following several
applications. 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 linings for
wear and evenly tighten wheel nuts in the
proper sequence to torque specifications. See
Capacities and Specifications 3261.
Brake pads should be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not
return to normal height, or if there is arapid
increase in pedal travel. This could be a sign that
brake service may be required.
Replacing Brake System Parts
A
lways replace brake system parts with new,
approved replacement parts. If this is not done,
the brakes may not work properly. The braking
performance can change in many ways if the
wrong brake parts are installed or if parts are
improperly installed.
Brake Fluid
The brake master cylinder reservoir is filled
w
ith GM approved DOT 4brake fluid as
indicated on the reservoir cap. See Engine
Compartment Overview 3190 for the location
of the reservoir.
Checking Brake Fluid
With the vehicle in P(Park) on alevel surface,
the brake fluid level should be between the
minimum and maximum marks on the brake
fluid reservoir.
There a
re only two reasons why the brake fluid
level in the reservoir may go down:
•
Normal brake lining wear. When new
linings are installed, the fluid level goes
back up.
•
A fluid leak in the brake hydraulic system.
Have the brake hydraulic system fixed.
With aleak, the brakes will not work well.
Always clean the brake fluid reservoir cap and
the area around the cap before removing it.
Do not top off the brake fluid. Adding fluid does
not correct aleak. If fluid is added when the
linings are worn, there will be too much fluid
when new brake linings are installed. Add or
remove fluid, as necessary, only when work is
done on the brake hydraulic system.
{ W
arning
If too much brake fluid is added, it can spill
o
n the engine and burn, if the engine is hot
enough. You or others could be burned, and
the vehicle could be damaged. Add brake
fluid only when work is done on the brake
hydraulic system.
