Yamaha FJR1300A(D) Service Manual page 250

When the main switch is turned to "ON", a
single pulse will be generated in the brake le-
ver "1". After the pulse is generated in the
brake lever, it is generated in the brake pedal
"2" twice.
TIP
A single pulse will be felt in the brake lever once,
then in the brake pedal twice. The second per-
son should confirm that the rear brake force is
released during the second pulse in the brake
pedal, third pulse overall, by manually applying
force to rotate the rear wheel. If the rear brake
force is released during the second pulse in the
brake pedal, the second person will be able to
rotate the rear wheel for 0.1 second.

NOTICE
• Check that the pulse is felt in the brake le-
ver once, and then in the brake pedal twice.
• If the pulse is felt in the brake pedal before
it is felt in the brake lever, check that the
brake hoses and brake pipes are connected
correctly to the hydraulic unit assembly.
• If the rear brake force is not released during
the second pulse in the brake pedal, but
during the pulse in the brake lever or during
the first pulse in the brake pedal, check that
the brake hoses and brake pipes are con-
nected correctly to the hydraulic unit as-
sembly.
