Braking
General information
What affects braking efficiency?
-
Operating conditions and driving habits
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing condit ions and driving habits
c::;, &. . On
vehicles that are either dr iven mostly in stop­
and-go city traffic or are driven hard, the
brake pads should be checked by your author­
ized Audi dea ler more often than specified in
the Warranty
& Maintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you should use the braking
effect of the engine. This way, you prevent un­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down continuously. Pump the brakes at inter­
vals .
Operating noise
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Due to the nature of the materia ls used in ce­
ramic brake rotors*, noises may become more
apparent at low speeds. .,..
