Brake Chamber Stroke
WARNING! Manual adjustment of automatic
slack adjusters is a dangerous practice that
could have serious consequences. It gives the
operator a false sense of security about the
effectiveness of the brakes. Contact the Ser-
vice Department at your dealership if the stroke
exceeds the above speci
fi
cations.
A stroke
exceeding these values may indicate a problem
with the slack adjuster or the brake foundation.

have any wheel service performed by an expert.
And stand away from the tire assembly while

Your tires are a very important part of your vehicle’s whole
braking system. How fast you can stop depends in large
measure on how much friction you get between the road
and your tires. In addition, keeping your tires in good con-
dition is essential to the safe, ef

cient operation of your ve-
hicle. Regular, frequent inspection and the right care will
give you the assurance of safe and reliable tire operation.
Here are some tips on maintaining your tires.
