Front Brake Fluid Level Check
With the motorcycle in an upright position, check
the fluid level.
It should be above the LWR mark (1). If the level
is at or below the LWR mark, check the brake pads
for wear (page 98).
Worn brake pads should be replaced. If the pads
are not worn, have your brake system inspected for
leaks.
If the pulling distance for the front brake lever
feels excessive, there is probably air in the brake
system and it must be bled. Refer to an official
Honda Shop Manual or see your Honda dealer for
brake bleeding.
Honda recommends using DOT4 Brake Fluid from
a sealed container, or an equivalent.
Other Checks:
Make sure there are no fluid leaks. Check for
deterioration or cracks in the hoses and fittings.
Rear Brake Fluid Level Check
With the motorcycle in an upright position, check
the fluid level.
It should be above the LOWER mark (1). If the
level is at or below the LOWER mark, check the
brake pads for wear (page 98).
Worn brake pads should be replaced. If the pads
are not worn, have your brake system inspected for
leaks.
If the travel for the rear brake pedal feels
excessive, there is probably air in the brake system
and it must be bled. Refer to an official Honda
Shop Manual or see your Honda dealer for brake
bleeding.
