Clutch - Porsche 928 1982 Owner's Manual

Brake fluid reservoir
The brake fluid reservoir is located in the
engine compartment.
The brake fluid reservoir has three cham-
bers: 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 be-
tween the MIN and MAX marks.
To add brake fluid, unscrew the cap. The
vent bore in the cap should be kept clean.

Every 2 years the brake fluid has to be re-
placed. See Maintenance Schedule.
Warning: Brake fluid is poisonous!
Caution: Brake fluid must not come into
contact with paintwork.
If brake fluid must be added to the reservoir,
use only new and unused DOT 3 or DOT 4
brake fluid that meets SAE specification J1703
and conforms to Motor Vehicle Safety Stan-
dard 116. Using any other brake fluid, or using
brake fluid that has absorbed moisture from
the open air, or brake fluid that is dirty, may
cause premature wear or unreliable braking
action.
Do not add or mix DOT 5 silicone type brake
fluid with the brake fluid in your car as severe
component corrosion may result. Such corro-
sion could lead to brake system failure.
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.
