WHEN TO RELINE BRAKES-New
brake linings are usually necessary after
three or four
adjustments,
when the brake
lining is worn down to the rivets which
fasten the lining to the brake shoe. Exposed
rivets will score brake drums and lead to
expensive
repairs.
Inspection of the lining after a brake drum has been removed is the
only way to tell when a brake reline is
necessary.
You can save by
asking your service man to inspect the brake shoes at the third adjust-
ment,
so you can see for yourself if relining is necessary.
When it ,is necessary to reline your brakes, have Pontiac Factory
Engineered Brake Shoe sets installed to make sure you get linings
engineered for your car and correctly ground and riveted to the shoes.
OTHER BRAKE SERVICE-As a general rule. the only brake
service you will need will be brake adjustments and relining at high
mileages.
However, if you notice anything unusual about your brakes
(squeaks,
grabbiness,
springy pedal, pulling to one side or one tire
sliding ahead of the others when brakes are
applied),
it's a good
safety precaution to take your car to a Pontiac service station
immediately and locate the cause.
PROLONGING THE LIFE OF YOUR BRAKES-Here are a few
suggestions to give you safe brakes at a minimum of expense:
1. When your car is new or when new linings have been installed,
apply brakes carefully the first few hundred miles until the lining
surfaces have acquired a smooth finish.
2.
In mountainous country. use a lower gear going downhill. This
allows the
engin~'
to do part of the braking and saves on your
brakes.
On Hydra-Matic equipped cars use the right hand DR
position or LO as
required.
~.
Have your brakes adjusted when you can push the brake pedal
within two inches of the floorboard. (One inch with power brakes.)
4. If you want to get the maximum service out of your brake lining,
have the wheels removed and all dust and dirt blown out of the
drums and the brake shoe mechanismsJubricated every time the
brakes are
adjusted.
It is poor economy to have
brakes'
adjusted
without performing this simple extra service. Removing the drums
also permits examination of the brake
lining.
5. Leave the car in gear in ordinary traffic stops until the car is
practically stopped. This lets the engine do a good share of the
braking job and adds miles to brake life.
