Brake Fluid Replacement; Drive Chain Slack Check - Yamaha XT500E Owner's Manual

8 Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor brake performance.
8 Be careful that water does not
enter the master cylinder when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
8 Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8 Have a Yamaha dealer check
the cause if the brake fluid level
goes down.
