2005 YAMAHA GRIZZLY 660 brake

8-105

Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reaction
and lead to poor brake performance.


Be careful that water does not enter the master
cylinder reservoirs when refilling. Water will sig-
nificantly lower the boiling point of the fluid and
may result in vapor lock.


Brake fluid may deteriorate painted surfaces or
plastic parts. Always clean up spilled fluid im-
mediately.


Have a Yamaha dealer check the cause if the
brake fluid level goes down.
