Brak e/clut ch fluid c ha nge
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) .
