Functioning of brake system
Your vehicle is equipped with a power
assisted hydraulic dual circuit Anti-Lock
brake system (ABS) with disc brakes at
the front and rear. Both circuits function
independently. Each brake circuit
operates one front and rear wheel
diagonally. On quattro models brake
circuits are split front and rear. This
design, together with other front axle
features, also helps to keep you on a
straight course when braking.
For further information regarding Anti-
Lock brake system see next page.
In the unlikely event of hydraulic failure of
one circuit,
push the brake pedal down
firmly and hold it in that position . A
mechanical linkage activates the second
circuit, and you will be able to bring the
vehicle to a stop.
WARNING
Failure of one brake circuit wit! impair
the braking capability resulting in an
increased stopping distance.
If one brake circuit fails, the other will still
operate. However, you will notice an
increased pedal travel when you step on
the brake. Should you encounter such
experience, bring your vehicle safely to a
full stop.
Avoid driving the vehicle and have it
towed to the nearest Audi dealer or
qualified workshop.
Brake operation and brake warning
light
Make it a habit to check the operation of
your brakes before driving. The brake
warning light will light up if the parking
brake is pulled and/or the brake fluid
level or the hydraulic brake booster
pressure is too low. For more details see
"Brake warning light" on page 50.
Keep in mind that the braking distance
increases very rapidly as the speed
increases. At 60 mph or 100 km/h, for
example, it is not twice but four times
longer than at 30 mph or 50 km/h. Tire
traction is also less effective when the
roads are wet and slippery. Therefore,
always maintain a safe distance.
Brake booster
The brake booster is supplied with
pressure from the hydraulic pump via the
hydraulic pressure reservoir. If the engine
is switched off or if the hydraulic pressure
supply should fail, the operating pressure
is retained. However, since the capacity
of the pressure reservoir is limited, it will
provide enough pressure for only a few
braking applications. If this should occur,
contact your authorized Audi dealer for
assistance.
WARNING
When the vehicle is moving with the
engine not running or in case of a
hydraulic system failure, more force
on the brake pedal is required to bring
the vehicle to a stop.
