µµ The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If the level is at or
below the MIN mark, your brake
system needs attention. Have the
brake system inspected f or leaks or
worn brake pads.
Check the f luid level in the brake
f luid reservoir monthly.
The brake f luid should be replaced
according to the time recommenda-
tion in the maintenance schedule.
Always use Honda Heavy Duty
Brake Fluid DOT 3. If it is not
available, you should use only DOT 3
or DOT 4 f luid, f rom a sealed
container, as a temporary
replacement. However, the use of
any non-Honda brake fluid can cause
corrosion and decrease the lif e of the
system. Have the brake system
f lushed and ref illed with Honda
Heavy Duty Brake Fluid DOT 3 as
soon as possible.
Brake f luid marked DOT 5 is not
compatible with your vehicle’s
braking system and can cause
extensive damage.
If it is not, slowly add proper f luid
until it starts to run out of the hole.
Reinstall the f iller plug and tighten it
securely.
The transf er assembly f luid should
be drained and ref illed with new f luid
accordingtothetimeanddistance
