BRAKES
BRAKE FLUID
Check brake fluid levels for both brake systems before each ride. Always
maintain brake fluid at the recommended level. Do not overfill.
The brakes should feel firm when they’re applied. Spongy or weak brakes may
indicate a fluid leak or low fluid level. A low fluid level may also mean that brake
pads are worn and need to be replaced. Do not operate the vehicle with spongy
or weak brakes. See your dealer for service.
WARNING
Operating the Tractor with a spongy brake can result in loss of braking, which
could cause an accident. Never operate the Tractor with spongy-feeling
brakes.
If the fluid level is low add DOT 4 brake fluid only. See the POLARIS Products
section for part numbers.
WARNING
An over-full master cylinder may cause brake drag or brake lock-up, which
could result in serious injury or death. Maintain brake fluid at the recommended
level. Do not overfill.
Under normal operation, the diaphragm extends into the reservoir as fluid level
drops. If the fluid level is low and the diaphragm is not extended, a leak is likely
and the diaphragm should be replaced. To ensure proper diaphragm operation,
always fill the reservoir as needed whenever the cover is loosened or removed.
Do not overfill.
WARNING
Never store or use a partial bottle of brake fluid. Brake fluid is hygroscopic,
meaning it rapidly absorbs moisture from the air. The moisture causes the
boiling temperature of the brake fluid to drop, which can lead to early brake
fade and the possibility of accident or severe injury. After opening a bottle of
brake fluid, always discard any unused portion.
