Checking The Brake Fluid Level - Yamaha Vmax VMX12N Owner's Manual

PERIODIC MAINTENANCE AND MINOR REPAIR
1. Minimum level mark

Checking the brake fluid level

Insufficient brake fluid may allow air to
enter the brake or clutch systems, pos-
sibly causing them to become ineffec-
tive.
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake flu-
id level may indicate worn brake pads
and/or brake system leakage. If the
brake level is low, be sure to check the
brake pads for wear and the brake sys-
tem for leakage.

NOTE:
To check the rear brake fluid level, re-
move panel B. (See page 6-9 for panel
removal and installation procedures.)
Observe these precautions:
l When checking the fluid level,
make sure that the top of the mas-
ter cylinder is level by turning the
handlebars.
l Use only the recommended quali-
ty brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or clutch
performance.
Recommended brake fluid: DOT 4

l Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking or clutch per-
formance.
The diaphragm will lose its shape
l
from the negative pressure if the
brake fluid level goes down too far.
Be sure to put the diaphragm back
in its original shape before install-
ing it into the master cylinder.
Be careful that water does not en-
l
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
