Brake and clutch fluid le ve l
The fluid lev el in the containe r must be
neither higher than the MAX mark nor

W hen topping up, ens ure max imum
cle anline ss , as contamination of the b ra ke/
clutch fluid can lead to function problems
in the braking s ys te m.
After corre cting the brak e/clutch fluid lev el,
have the cause of brake/clutch fluid loss

Brake /clutch fluid is hygroscopic, i.e . it
absorbs water. If the brak es be come hot,
s uc h as whe n driving on long downhill
stretches, va pour bubbles can occur in the
water, which can have an extrem ely
adv ers e e ffe ct on braking power
( dep en di n g o n t h e p ro p o r t i o n o f w a t e r) .
