1993 PONTIAC GRAND-AM brakes

Brake Master Cylinder
Your brake master cylinder is here. It is
filled with DOT-3 brake fluid.
There are only two reasons why the
brake fluid level in your master cylinder
might go down. The first is that the
brake fluid goes down to an acceptable
level during normal brake lining wear.
When new linings are put in, the fluid
level goes back up. The other reason
is that fluid is leaking
out
of the brake system. If it is, you
should have your brake system fixed,
since a leak means that sooner or later
your brakes won’t work well, or won’t
work at all.
So, it isn’t a good idea to “top off’ your
brake fluid. Adding brake fluid won’t
correct a leak.
If you add fluid when
your linings are worn, then you’ll have
too much fluid when you get new brake
linings. You should add (or remove)
brake fluid, as necessary,
only when
work is done on the brake hydraulic
system.

Brake Master Cylinder (CONI)
I If you have too much brake
fluid, it can spill
on the
engine. The fluid will burn
if the
engine
is hot enough. You or
others could be burned, and your
vehicle could
be damaged. Add
brake fluid only when work is
done on the brake hydraulic
system.
When your brake fluid falls to a low
level, your brake warning light will
come on. See the
Index under Brake
System Warning Light.
What to Add:
When you do need brake fluid, use only
DOT-3 brake fluid-such as Delco
Supreme
ll@ (GM Part No. 1052535).
Use new brake fluid from a sealed
container only.

Replacing Brake System Parts
The braking system on a modern 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.
Vehicles we design and test have top-
quality
GM brake parts in them, as your
Pontiac does when
it is new. When you
replace parts of your bralung system-
for example, when your brake linings
wear down and you have to have new
ones put in-be sure you get new
genuine
GM replacement parts. If you
don't, 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've
come to expect can change
in many
other ways
if someone puts in the wrong
replacement brake parts.

When you are doing this check, your vehicle could begin to move. You or others could be
- b injured and property could be damaged. Make sure there is room in front of your vehicle
in case it begins to roll. Be ready to apply the regular brake at once should the vehicle begin to
move.
Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular
brake, set the parking brake.
To check the parking brake: With the engine running and the transaxle in N (Neutral), slowly
remove foot pressure from the regular brake pedal.
Do this until the vehicle is held by the
parking brake only.
To check the P (Park) mechanism’s holding ability: Shift to P (Park). Then release all brakes.
At least every spring, use plain water to flush
any corrosive materials from the underbody. Take
care to clean thoroughly any areas where mud
and other debris can collect.

Section C: Periodic Maintenance Inspections
Listed below are inspections and services which should be perfo\
rmed at least twice a year (for instance, each spring and fall).
You should let your GM dealer’s service department or other qualified service center do these jobs: Make sure any necessary
repairs are completed at once.

WHAT SHOULD BE DONE I
Inspect the front and rear suspension and steering system for \
damaged, loose or missing parts,
signs
of wear, or lack of lubrication. Inspect the power steering lines and hoses for proper
hookup, binding, leaks, cracks, chafing, etc. Clean and then in\
spect the drive axle boot seals for damage, tears or leakage. Replace seals if necessary.
Inspect the complete exhaust system. Inspect the body near the \
exhaust system. Look for broken,
damaged, missing or out-of-position parts
as well as open seams, holes, loose connections, or
other conditions which could cause a heat build-up in the floor pan or could let exhaust fumes
into the vehicle. See the
Idex under EnRine Exhaust.
Inspect the throttle linkage for interference or binding, and for damaged or missing parts.
Replace parts as needed.
Inspect the complete system. Inspect brake lines and hoses for \
proper hookup, binding, leaks,
cracks, chafing, etc. Inspect disc brake pads for wear and rot\
ors for surface condition. Also
inspect drum brake linings for wear and cracks. Inspect other brake parts, including drums,
wheel cylinders, calipers, parking brake, etc. The parking brake is self-adjusting and no manual
adjustment is required,
You may need to have your brakes inspected more often if your driving
habits or conditions result in frequent braking.
NOTE:
A low brake fluid level can indicate worn disc brake pads which \
may need to be
serviced. Also, if the brake system warning light stays on or comes on, something may be wrong
with the brake system. See the
Index under Brake System Warning Light. If your anti-lock brake
system warning light stays on, comes on or flashes, something may be wrong with the anti-lock
brake system. See the
Index under Anti-Lock Brake System Warning Light.
