Front and rear disc brake maintenance

1. Brake oil fluid.
Check to see if the brake oil level is lower than the 'Low' marker line (2) by observing the observation point (1) of brake
oil master pump. If it is Below the LOW marker line, add more brake oil to make the level 3-5mm higher than this marker
line. Make sure it doesn't exceed the maximum level. Every time the level is lowered to approach "LOWER" marker line
(2), check if the braking lining (pad) is worn in. If the wear extent of the braking lining does not exceed limits, check it for
leakage and consult with the nearest service center of our company.
2. Steps and method for replacement of brake oil
Firstly, discharge existing brake oil in the system with the following steps.
(1). Put the oil cylinder (on the handlebar) of master pump in horizontal
position and open the oil well cover and washer.
(2). Remove the brake caliper and put the bleeder nozzle in the lowest
position;
(3). Unscrew the bleeder nozzle to make the brake oil flow out freely
(4). Add 30 - 50ml of new brake oil into the oil cylinder and empty the oil cylinder after old oil cylinder does not flow out;
(5). Screw down the bleeder nozzle, wipe the brake oil off the brake caliper and mount the brake caliper on the motorcycle.
Secondly, add new special brake oil into the oil cylinder as the following steps:
1. Slip a transparent hose on the bleeder nozzle (this hose should be closely fitted to the bleeder nozzle) and
unscrew the bleeder nozzle through about 120 degrees;
2. Add new brake oil to the oil cylinder of master pump, make the brake oil flow out freely (do not move the handle) till no
air bubble is in the brake oil flowing from the bleeder nozzle, and screw down the bleeder nozzle;
3. Move the handle, and repeat Step 2 till the desired effect is achieved. Finally, put the oil well washer and cover
and tighten the screws of the oil well cover.
Caution
1. When replacement or adding oil please use authentic DOT3 or DOT4 special brake oil. 2 - Do not mix several types of
