MASTER CYLINDER/BRAKE FLUID

An over-full master cylinder may cause brake drag or brake lock-up, which
could result in an accident. Maintain brake fluid at the recommended level. Do
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 brake failure, which could result in an accident. After
opening a bottle of brake fluid, always discard any unused portion.
Check the brake fluid in the master cylinder before each ride.
