Brakes

The hydraulic disc brakes (front) and a single hydraulic mechanical
disc brake (rear) on your ATV dissipate heat generated by the friction
of the brake pads on the discs as the wheels are slowed.
As the brake pads wear, brake fluid level will drop. A leak in the
system will also cause the level to drop.
There are no adjustments to perform, but fluid level and pad wear
must be inspected periodically. The system must be inspected
frequently to ensure there are no fluid leaks.
If the right brake lever or brake pedal freeplay does not feel within
the normal range while riding, check the brake pads for wear
(page 187).
Worn pads should be replaced. If the pads are not worn beyond the
recommended limit, there is probably air in the brake system. See
your dealer to have the air bled from the system.
Brake Fluid Recommendation
brake fluid DOT 4 Brake Fluid
The recommended brake fluid is DOT 4 Brake Fluid, or any brake
fluid of equal quality and performance. Use fresh brake fluid from a
sealed container. Be sure to read the label before opening the sealed
container. An opened container may be contaminated or may have
absorbed moisture from the air.
