WARNING
EWB02572Operating with improperly serviced or ad-
justed brakes could lead to a loss in brak-
ing ability and an accident. EBU35150Checking the front and rear brake padsCheck each brake pad for damage and mea-
sure the lining thickness. If a brake pad is
damaged or if the lining thickness is less than
1.0 mm (0.04 in), have a Yamaha dealer re-
place the brake pads as a set.
The wheels need to be removed to check the
brake pads. (See pages 9-57, 9-59 for wheel
removal and installation procedures.)
EBU32490Checking the parking brake padsEach brake pad is provided with a wear indi-
cator groove, which allows you to check the
brake pad wear without having to disassem-
ble the brake. If a brake pad has worn to the
point that the wear indicator groove has al-
most disappeared, have a Yamaha dealer re-
place the brake pads as a set.1. Lining thickness
