Checking the front and rear
brake pads
The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and

lubrication chart.

Front brake pads
1. Brake pad wear indicator groove
The front brake calipers are equipped
with two sets of brake pads.
Each front brake pad is provided with
one or two wear indicator grooves,
which allow you to check the brake pad
wear without having to disassemble the
brake. To check the brake pad wear,
check the wear indicator grooves. If a
brake pad has worn to the point that a
EAU22390 wear indicator groove almost appears,
have a Yamaha dealer replace the
brake pads as a set.
