MAINTENANCE
BRAKE FLUID PRECAUTIONS
WARNING
Using the wrong fluid or allowing air or contaminants into the fluid system can
damage the system seals or result in a malfunction that could lead to serious
injury or death. Use only DOT 4 brake fluid from a sealed container.
Do not operate the front brake with the reservoir cover removed. Fluid could
overflow from the reservoir and allow air to enter the system. Air in the brake
system could cause the brakes to malfunction.
An over-full reservoir 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.
After opening a bottle of brake fluid, always discard any unused portion. Never
store or use a partial bottle. 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
NOTICE
Brake fluid will damage painted surfaces and plastic parts. Always clean spilled
brake fluid immediately with water and a mild detergent.
