Brake Booster; Antilock Brake System (Abs) - Skoda Superb Owner's Manual

180 Intelligent Technology
WARNING

Only apply the brakes for the purpose of drying and cleaning the brake discs
if the traffic conditions permit this. Do not place any other road users in jeop-
ardy.

When retrospectively mounting a front spoiler, solid wheel hubs etc. one
must ensure that the air supply to the front wheel brakes is not reduced other-
wise the braking system could run too hot.

Allow for the fact that new brake pads do not achieve their full braking effi-
ciency until approximately 200 kilometres. New brake pads must be first "run in"
before they develop their optimal friction force. You can, however, compensate
for this slightly reduced braking force by increasing the pressure on the brake
pedal. This guideline also applies to any new brake pads installed at a future
date.
Caution

Never allow the brakes to rub by applying slight pressure if you do not wish to
brake the vehicle. This causes the brakes to overheat and can also result in a longer
braking distance and excessive wear.

Before negotiating a steep downhill section, please reduce your speed, shift
down into the next lower gear (manual gearbox) or select a lower driving stage
(automatic gearbox). This enables you to make full use of the braking power of the
vehicle and reduces the strain on the brakes. Any additional braking should be done
intermittently, not continuously.
Note
The brake light flashes automatically in case of an emergency braking at speeds
greater than 60 km/h or with the intervention of the ABS, which lasts longer than
1.5 seconds. After the speed was reduced below 10 km/h or the vehicle was stopped,
the brake light stops flashing and the hazard warning light system switches on. The
hazard warning light system is switched off automatically after accelerating or
driving off again.

Brake booster

The brake booster boosts the pressure which you generate with the brake pedal.
The necessary pressure is only generated when the engine is running.
WARNING

Never switch off the engine before the vehicle is stationary.

The brake booster only operates when the engine is running. Greater phys-
ical effort for braking is required when engine is switched off. Because if you do
not stop as normal, this can cause an accident and severe injuries.

While stopping or braking with a vehicle with a petrol engine and manual
transmission in the low rev range, press down on the clutch pedal. If you fail to
do so, the result may be an impairment of the function of the power brake. You
will apply a greater force to the brake pedal which you are usde to - danger of
accident!

Antilock brake system (ABS)

ABS prevents the wheels locking when braking.
General
The ABS contributes significantly to enhancing the active safety of your vehicle.
Compared to a car not fitted with the ABS brake system, you are able to retain
optimal steering ability even during a full brake application on a slippery road
surface because the wheels do not lock up.
You must not expect, however, that the braking distance will be shorter under all
circumstances as a result of the ABS. The braking distance for example on gravel
and fresh snow, when you should anyway be driving slowly and cautiously, will be
longer.
Operating principle
The brake pressure will be reduced on a wheel which is rotating at a speed which is
too low for the speed of the vehicle and tending to lock. This control cycle is notice-
able from a pulsating movement of the brake pedal which is accompanied by
noises. This is consciously intended to provide the driver with the information that
the wheels are tending to lock (ABS control range). You must always keep the brake
pedal depressed to enable the ABS to optimally control the brake application in this
braking range. Never interrupt the application of the brakes!
As soon as the vehicle speed has increased to about 20 km/hour an automatic test
procedure is conducted during which you will be able to hear a pumping noise for
about 1 second.
