Liquid deposit back brake
REAR BRAKE
Periodically check the brake fluid level in the reservoir
situated on top of the rear brake master cylinder and
under the rear right hand panel, to top up, use Dot 4
brake fluid.
If the reservoir is empty please go to your local Rieju
dealer.
BRAKE FLUID LEVEL AND BRAKE PAD WEAR
Check that the level of brake fluid is correct, if not, Check
for brake pad wear. If the pad material is less than 2mm
thick, the pads should be replaced. If the pads are not
worn out, top up the brake reservoir with brake fluid.
(WARNING Brake fluid is corrosive and will damage
paintwork, if spilt wash off with water immediately)
Always remember that the above must be carried out by a RIEJU official service.
