Brake fluid
Caution:
●This inspection should be completed by a quali fied
maintenance organization.
●It is strictly forbidden to directly flush the main pump with
high-pressure water.
●After disassembly, make sure that all parts are installed
correctly.
●It is strictly forbidden to mix in water, dust, impurities and
silicic acid or petroleum-based liquids, otherwise it will cause
serious damage to the brake system.
●This vehicle uses DOT 4 brake fluid, and it is forbidden to
mix it with other brake fluids.
●Wear protective gloves/protective clothing/protective
goggles/protective masks.
●Brake fluid must be used in time after opening, seal and
moisture-proof measures must be taken when storing; it is
recommended not to exceed 1 month. Inferior or damp
brake fluid will cause adverse effects on the brake system,
and may cause brake failure when the impact is severe.
●The brake fluid should be prevented from dripping on the
paint surface of the cover or the surface of the parts. If it is
accidentally splashed, it should be rinsed with water
immediately.
●If you accidentally swal low the brake fluid, you should
contact the poison control center or hospital immediately; if
you accidentally get the brake fluid into your eyes, rinse with
water and seek medical attention immediately.
●Brake fluid must be kept away from children and pet s.
●The vehicle must be parked on a flat and stable ground or a
lifting platform.
1. Add brake fluid to the main pumps of the front
and rear disc brakes
The M125/350 steps are similar to the M310, taking the
M310 as an example.
a. Adding brake fluid to the main pump of a disc brake is
taken as an example for description. The steps for refilling
the rear brake main pump are the same.
b. Place the vehicle horizontally.
c. Wrap around the main pump with oil-resistant plastic
film to prevent the brake fluid from dripping onto the surface
of the parts and damaging the paint layer.
d. After wearing waterproof gloves, use a Phillips
screwdriver to remove the bolt①, and remove the upper
cover②, the cover③, and the sealing rubber gasket④.
e. Use the brake fluid water content tester to measure the
water content, if it is more than 2%, all brake fluid needs to
be replaced; if it is less than or equal to 2%, add newly
opened DOT 4 brake fluid to the transparent observation
window of the front disc brake main pump 3/4 places. It is
recommended that the water content should be less than
1.5%. Total 0.23L

TOTAL HBF 4 (DOT 4) brake fluid is added to this
vehicle from the factory.

tester. The picture comes from the Internet and the

not use it for other purposes.
f. Reassembly can only be done after the foreign objects
have been cleaned up.
2. Replace the brake fluid
Refer to the steps of adding brake fluid. If the measured
water content is greater than 2%, the brake fluid needs to be
replaced. M310 this inspection should be done every 5000
kilometers (3107 mile) or every 15 months. M125/350 this
inspection should be done every 4000 kilometers (3107 mile)
or every 15 months. It is recommended to replace the brake
fluid every 2 years. If the brake fluid is not replaced for a long
time, flocs will form to block the oil pipe, the oil hole of the
main pump of the disc brake or the piston will become stuck,
which will cause the braking effect to deteriorate or fail,
which will affect driving safety.
2.1 Replace the front brake brake fluid
a. Wrap around the front brake main pump with oil-
resistant plastic film, as shown in the previous section.
b. Pull out the rubber cap of the vent nozzle ①, and put on
8# torx wrench. Use a 6mm (0.23 in) hose to fit the vent②,
being careful not to remove the torx wrench.
