brake pads CHEVROLET AVEO 2007 1.G Owners Manual

Notice:
Using the wrong uid can badly damage
brake system parts. For example, just a
few drops of mineral-based oil, such
as engine oil, in the brake system can
damage brake system parts so badly that
they will have to be replaced. Do not
let someone put in the wrong kind of uid.
If you spill brake uid on your vehicle’s
painted surfaces, the paint nish can
be damaged. Be careful not to spill brake
uid on your vehicle. If you do, wash it
off immediately. SeeWashing Your Vehicle
on page 349.
Brake Wear
Your vehicle has front disc brakes and could have
rear drum brakes or rear disc brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the
brake pads are worn and new pads are needed.
The sound can come and go or be heard all
the time your vehicle is moving, except when you
are pushing on the brake pedal firmly.
{CAUTION:
The brake wear warning sound means that
soon the brakes will not work well. That
could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.
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.
301

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 inCapacities and Specifications on
page 368.
If you have rear drum brakes, they do not have
wear indicators, but if you ever hear a rear brake
rubbing noise, have the rear brake linings
inspected immediately. Also, the rear brake drums
should be removed and inspected each time
the tires are removed for rotation or changing.
When you have the front brake pads replaced,
have the rear brakes inspected, too.
Brake linings should always be replaced as
complete axle sets.
SeeBrake System Inspection on page 395.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 you make a moderate brake stop, the
disc brakes adjust for wear. If you rarely make
a moderate or heavier stop, then the brakes might
not adjust correctly. If you drive in that way,
then — very carefully — make a few moderate
brake stops about every 1,000 miles (1 600 km),
so the brakes will adjust properly.
If the brake pedal goes down farther than normal,
the rear drum brakes might need adjustment.
Adjust them by backing up and firmly applying the
brakes a few times.

Fuel System Inspection
Inspect the complete fuel system for damage
or leaks.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if
they are cracked, swollen or deteriorated.
Inspect all pipes, fittings and clamps; replace as
needed. Clean the outside of the radiator and
air conditioning condenser. To help ensure proper
operation, a pressure test of the cooling system
and pressure cap is recommended at least once
a year.
Brake System Inspection
Inspect the complete system. Inspect brake lines
and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Inspect disc brake pads for
wear and rotors for surface condition. Also inspect
drum brake linings for wear and cracks. Inspect
other brake parts, including drums, wheel
cylinders, calipers, parking brake, etc. Check
parking brake adjustment. You may need to have
your brakes inspected more often if your driving
habits or conditions result in frequent braking.
