Check and Adjust

Check the brake liquid level

Check the level of the reservoir, it should be between "MAX" and

"MIN".

If the level of the liquid is too low, check whether the brake system is

leaking.

If the brake warning light is till on when releasing the hand brake rod,

check whether the parking brake control system is adjusted to the right
position.

Check the brake pipe

Note:：
If the leakage is from the joints, tighten or replace the damaged parts.

1.Check whether the brake piping is broken or aging or has other

damages, replace the parts if necessary.

2.Depress the brake pedal to the end to check whether the oil is

leaking when the engine is in running.

Brake liquid replacement

Fill up with "901-B" brake liquid.

1.Use a nylon pipe to connect each exhaust valve.

2.Exhaust the brake liquid by depressing the brake pedal.

3.Add new brake liquid until it flows out from each exhaust valve. 

Exhaust out the oil from hydraulic system with the same

steps and add new liquid. Exhausting steps are refereed to
"Exhaust" part.

Note:
Do not reuse the exhausted and unclean liquid.
Be careful not spray the brake liquid on the painted area, it will

destroy the painting film. If you do it carelessly, clean it at once with
water.

Exhaust

Note:
Monitor the level of the liquid in process of exhausting.
Add new liquid of  "901-4" in to the reservoir to assure

it is always full during the whole process.

Place a container under the main pump to avoid liquid

coming out.

1.Use a nylon pipe to connect the exhaust valve.

2.Depress the pedal to the end several times.

3.Maintain the pedal at the end, loosen the valve to exhaust.

4.Tighten the exhaust valve.

5.Release off the pedal slowly.

6.Repeat the 2-5 steps until pure liquid flowing out of the

exhaust pipe.

Exhaust following the steps below:

Left rear wheel → right rear wheel → left front wheel →

right front wheel

Disassembly

Note:
Be careful not spray the brake liquid on the painted

area, otherwise it will damage the painting surface; if it
dose, clean it immediately with clean water.

Avoid bending, twisting and stretching of all the hoses

too much when disassembling.

1.Use a nylon pipe to connect the exhaust valve.

2.Depress the pedal several times to exhaust all the liquid

out of the valve.

3.Loosen the nut of the hose mouth connected with the brake.

4.Whenever cut off the hydraulic pipes, block the open with clean staff to

avoid dust entering.

Check

Check whether there is any crack, wear of the brake piping (pipes and

hoses), replace if there is.

Installation

Note:
Add new liquid of "901-4".
Do not use exhausted and unclean liquid.

1.Tighten all the expansion nuts and bolts.

                Tightening torque of the nuts: 15~18N.m

               Tightening torque of the bolts: 17~20N.m

2.Add new liquid until it flows out from the valve.

3.Exhaust air based on the above steps.
