Any absorbed moisture can cause a dangerous
loss of braking performance." If the vehicle requires frequent refilling, there
may be a leak. If you suspect a problem, have
the vehicle checked at your SUBARU dealer.
" Never use different brands of brake fluid to-
gether. " When adding brake fluid, be careful not to al-
low any dirt into the reservoir. " Never splash the brake fluid over painted sur-

Checking the clutch pedal free play
1) 0.16 – 0.51 in (4.0 –13.0 mm)

until you feel resistance, and check the free play.

the brake pads wear close to their service limit, the
wear indicator makes a very audible scraping noise

brake pedal, have the brake pads serviced by your
SUBARU dealer as soon as possible.
