Clutch - Porsche 928 S 1984 Owner's Manual

Brake fluid reservoir
The brake fluid reservoir is located in the en-
gine compartment.
The brake fluid reservoir has three chambers:
one for each of the dual brake circuits, and
one for the clutch.
Check the brake fluid level regularly. Since the
reservoir is transparent, the fluid level can be
checked without removing the filler cap. The
fluid level should always be between the MIN
and MAX marks.
To add brake fluid, unscrew the cap. The vent
bore in the cap should be kept clean.

If the brake fluid level should drop below the
MIN mark, the central warning light and the
brake fluid warning light will flash (see "Cen-
tral warning light system").
Pull off the road, stop the engine and add
brake fluid immediately or contact the
nearest Porsche dealer to have the cause
located and corrected.
WARNING
• Every 2 years the brake fluid has to be
replaced. See your Warranty & Mainte-
nance booklet.
• If brake fluid must be added to the reser-
voir, use only new and unused DOT 3 or
DOT 4 brake fluid that meets SAE spe-
cification J1703 and conforms to Motor
Vehicle Safety Standard 116.
• Do not use any other brake fluid or brake
fluids that have absorbed moisture from
the open air, or brake fluid that is dirty.
It may cause premature wear or unre-
liable braking action.
• Do not add or mix DOT 5 silicone type
brake fluid with the brake fluid in your
vehicle as severe component corrosion
may result. Such corrosion could lead
to brake system failure.
• The brake warning light does not indi-
cate brake fluid level. Check fluid level
between regular maintenance services.
• Brake fluid is poisonous. Brake fluid is
also harmful to the paint of your vehicle.

(where applicable)
The reservoir is located in the engine com-
partment in front of the radiator.
To avoid paint damage, we recommend the
exclusive use of a "special silicone remover"
cleaning agent. Clear water and anti-freeze
will not be sufficient.
Your Porsche dealer can advise you which
product to use.
