Adjusting The Brake Pedal Position And Free Play - Yamaha TT-R125Y Owner's Manual

After adjusting the brake lever
free play, check the free play and
make sure that the brake is
working properly.
A soft or spongy feeling in the
brake lever can indicate the
presence of air in the hydraulic
system. If there is air in the
hydraulic system, have a
Yamaha dealer bleed the system
before operating the motorcycle.
Air in the hydraulic system will
diminish the braking
performance, which may result
in loss of control and an
accident.
