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

be moist or even have a coating of ice on them in winter. You should dry the brakes as
soon as possible by applying and releasing the brakes several times.
There also may be a certain delay before the full braking efficiency is available when
driving on roads which have been treated with road salt if you have not used the
brakes for some considerable time beforehand. The layer of salt on the brake discs and
brake pads must first be rubbed off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on the bake pads occur if the vehicle has been
parked for a long period and if you do not make much use of the braking system.
We recommend cleaning the brake discs by firmly applying the brakes at a fairly high
speed if you do not make much use of the braking system or if surface corrosion is
present 
.
Faults in the brake surface
If you notice that the braking distance has suddenly become longer and that the brake
pedal can be depressed further, it is possible that a brake circuit of the dual-circuit
brake system has failed. Drive, in such cases, to the nearest specialist garage without
delay in order to have the problem rectified. Drive at a reduced speed while on your
way to the dealer and adapt your style of driving to the higher brake pedal pressure
required.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system. The level
of the brake fluid is monitored electronically  page 31, "Brake system ".
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,
WARNING (continued)
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, reduce your speed, shift down into the
next lower gear. 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 intermit-
tently, not continuously.

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.

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 vehicle 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.
