Brake fluid
In the course of time, the brake fluid absorbs water from the ambient air. If
there is too much water contained in the brake fluid, the brake system could
be damaged. In addition, the boiling point of the brake fluid is significantly
lowered. When the brake fluid contains too much water and the brakes are
subject to considerable forces, bubbles of water vapour can form in the
system. These bubbles of water vapour can significantly reduce braking
power, notably increasing braking distance, and could even result in the total
failure of the brake system. Ensuring that the brake system is always func-
tioning correctly is essential for your own safety and the safety of other road
users .
Brake fluid specifications
SEAT have developed a special brake fluid optimised for the brake systems of
their vehicles. To ensure the optimum working of the brake system, SEAT
recommends the use of brake fluid in accordance with the VW 501 14
standard. If this brake fluid is not available or another brake fluid is used for
different reasons, use a brake fluid that complies with the United States
standard FMVSS 116 DOT 4 or the German standard DIN ISO 4925 CLASS 4
.
Brake fluids conforming to the standard VW 501 14, fulfil the American
requirements of the FMVSS 116 DOT 4 standard and the German DIN ISO
4925 CLASS 4 standard. However, fluids that comply with the American
FMVSS 116 DOT 4 standard or the German DIN ISO 4925 CLASS 4 standard do
not necessarily comply with the VW 501 14 standard. Always check the infor-
mation on the brake fluid container and ensure that you are using suitable
brake fluid.
A suitable brake fluid can be obtained from Authorised Service Centres.
Brake fluid level
The level of the brake fluid should always be between the MIN and MAX
marks, or above the MIN mark .
It is not always possible to check the level of the brake fluid, as in some
models the engine components make it difficult to see the brake fluid reser-
voir. If you cannot read the exact brake fluid level, consult a specialist.
The brake fluid level drops slightly when the vehicle is being used due to wear
of the brake pads and the automatic readjustment of the brake.
Changing the brake fluid
The brake fluid should be changed in accordance with the instructions given
in the Maintenance Programme. Have the brake fluid changed by a qualified
workshop. SEAT recommends visiting a qualified workshop. This means that
only brake fluid complying with the required specifications will be used.
WARNING
If the brake fluid level is low or unsuitable/old brake fluid is used, the brake
system may fail or braking power will be reduced.
x Check the brake system and the brake fluid level regularly!
x The brake fluid should be changed regularly in accordance with the
instructions given in the Maintenance Programme.
