fit together to restore normal grip and to make the brake
fluid circulate stably.
●The braking distance may be longer than the original
braking distance after replacing the new brake disc or brake
pad. It needs to be used for about 300 kilometers (186 mile).
Good braking effect. Allow enough braking distance before
running in sufficiently to ensure driving safety.
●The brake pads must be replaced in pairs, only replacing
one side will cause uneven braking.
●If the position of the brake pads is incorrect, it is forbidden
to operate the brake handle. Otherwise, it will be difficult to
reset the piston and may cause brake fluid leakage.
2. Check the front and rear brake switches
2.1 Check the brake switch
Hold the brake handles of the main pumps of the front and
rear disc brakes respectively, and observe whether the rear
brake lights are on. If it does not light, you need to
investigate: whether the brake switch is faulty; whether the
rear brake light is faulty; whether the fuse has blown;
whether the circuit is open.
2.2 Replace the brake switch
Take the replacement of the rear brake switch as an
example to explain.
a. Pull out the two plugs of the brake switch in the
direction of the arrow without distinguishing the positive and
negative poles.
b. Use a Phillips screwdriver to remove the bolt① to
remove the rear brake switch

.
c. Replace with a new switch, pay attention to align the
switch boss and the limit hole of the brake main pump.
The replacement procedure of the front brake switch is the
same as that of the rear brake switch. The throttle cable
needs to be removed to facilitate the removal of the bolt①.
3. Lubricate the movable parts of the brake
handle
3.1 Lubricate the front brake handle.
a. Use a 10# torx wrench to rotate counterclockwise to
remove the nut③.
b. After grasping the handle, use a 5# inner hexagon
counterclockwise rotation to remove the bolt①; remove the
brake handle.
c. Wipe the handle pusher and the outer end of the piston
with a clean non-woven cloth (the position shown in
Figure②), and apply high vacuum silicone grease evenly.
d. Wipe clean the bolt①, and apply high vacuum silicone
grease evenly.
e. Reinstall.
3.2 After lubricating the brake handle
Refer to the above method to lubricate the rear brake
handle.
3.3 Replacing the brake handle
Refer to the previous steps to remove the nut③ and
bolt① to replace the new brake handle.
4. Adjust the brake handle
In order to adapt to more drivers driving this model, it is
equipped with an adjustable brake handle. Take the right
front brake handle as an example. Push the end of the handle
to the end in the direction of the arrow, and adjust the wheel
clockwise by hand. The extension of the push head will
increase the distance between the handle and the rubber
sleeve, and vice versa. The adjustment method of the rear
brake handle on the left is opposite to that on the right.
