Back brake

located on the top of the master cylinder of the rear brake and
under the rear right panel, to recharge.
ATTENTION: If the tank is empty, contact your official RIEJU
dealer
Brake fluid level and wear of brake pads
Check that the brake fluid level is correct, otherwise check the
brake pads for wear. If the pad material is less than 2 mm
thick, the pads should be replaced. If the pads are not worn, fill
the brake reservoir with brake fluid.
ATTENTION:
The brake fluid is corrosive and will damage the paint, if it
is spilled, immediately wash it with water.
