WARNING：
Brake fluid, if it leaks, will interfere with safe running and immediately discolor painted surfaces.
Check the brake hoses for cracks and hose joints for leakage before riding.
Brake pads
Wearing condition of brake pads can be checked by observing
the limit line marked on the pad. When the wear exceeds the
limit mark, replace the pads with new ones.
Bleeding air from the brake fluid circuit
Air trapped in the fluid circuit acts like a cushion to absorb a large
proportion of the pressure developed by the master cylinder and thus
interferes with the full braking performance of the brake caliper. The
presence of air is indicated by “sponginess” of the brake lever and
also by lack of braking force. Considering the danger to which such
trapped air exposes the machine and rider, it is essential that, after
remounting the brake and restoring the brake system to the
normal condition, the brake fluid circuit be purged of air in the
following manner:
• Fill up the master cyliner reservoir to the upper end of the
inspection window. Replace the reservoir cap to prevent entry of dirt.
• Attach a pipe to the caliper bleeder valve, and insert the free
end of the pipe into a receptacle.
□Bleed air from the bleeder valve.
Squeeze and release the brake level several times in rapid succession.
And squeeze the lever fully without releasing it. loosen the bleeder valve
by turning it a quarter of a turn so that the brake fluid runs into the
receptacles: the will remove the tension of the brake lever causing it to
touch the handlebar grip. Then, close the valve, pump and squeeze the
lever, and open the valve. Repeat the process until the fluid flowing
into the receptacle no longer contains air bubbles.
