Wheel
General tire balancing procedures
Clean out the accumulated dirt and debris from the inside of the rim.
Warning:
The gravel on the tread must be eliminated to avoid flying out and injuring the operator when
undergoing rotational balancing. This is also a good way to acquire better balance. First thoroughly
inspect the tire's damaged condition, then according to the balancing device manufacture's
recommendations, carry out the balancing operation.
Off-vehicle balancing
Most off-vehicle balancers are more accurate and convenient than on-vehicle rotational balancers. They are
also able to perform dynamic (two sided) balancing. Although it does not correct drum brake and brake disc
imbalance like on-vehicle balancing, it achieves the same effect based on its accuracy.
On-vehicle balancing
On-vehicle balancing is different based on equipment and tool manufacturer. Therefore, when performing
balancing operations, be sure to comply to each manufacturer's operating\
instructions.
Warning: Control the wheel rotation speed to make sure the speedometer stays within 55 km/h.
This restriction is necessary because when a driven wheel slides while the other one stays still, the
speedometer will display only half of the actual wheel speed. When a wheel is sliding, be extremely
careful, because sliding wheels can reach very high speeds. This may lead to the tire rubber peeling
or differential damage, which may cause serious personal injury, or damage to the vehicle.
Tire installation and removal
• Install or remove tires with a tire changer. When operating machinery, make sure to comply to the machine
manufacturers operation manual. Please do not change tires merely with manual hand tools or tire installation
crowbars. This will damage the tire chafer or the vehicle wheel's rim.
• Use a wire brush or coarse steel wool to clean off grease and old rubber, as well as light rust or corrosion from
the rim tire bead's tire chafer seat. Before tire installation or removal, first use the indicated tire lubricant to
thoroughly lube the tire chafer portions one time.
• After installing the tire, inflate it to the specified pressure and make\
sure the tire bead is properly seated.
Warning: Do not over-inflate the tire. If the tire bead severally expands and exceeds the safety limit,
it may burst and cause serious personal injury. While inflating, do not exceed the specified pressure.
If the specified pressure does not allow the tire bead to sit properly, deflate the tire, re-lubricate, and
then re-inflate.
Spare tire usage
• Spare tire standard inflation pressure: 420 kPa.
• Spare tire pressure measurements should be taken under normal temperatur\
e conditions.
• After inflating the spare tire, soapy water should be used to check if the air nozzles core is leaking air, then
lock on the air nozzle cap.
• The spare tire should always be kept in a useable state. Check the air p\
ressure at least once a month.
• When the spare tire's working limit, indicated by the remaining pattern's depth, reaches 1.6 mm (and its pat-
tern groove bottom protrudes to the same level), for your safety, please stop using the spare tire.
Caution:
• The "" symbol on the tire bead of the spare tire in-
dicates the set position of the wear index (shown on
the left).
• The spare tire's maximum driven speed is 80 km/h,
and maximum distance 200 km per trip.
• Each vehicle is allowed to use only one spare tire.
• The spare tire is only used as a temporary backup.
Please go to a professional service station immediately
to get the initial tire repaired or replaced.

(e) Make sure not to let the system valves block the air bleeding.
(f) When the brake fluid that flows out of the hose or connector has no bubbles, it means that the air
in the system has been exhausted. There is still air inside the system if the hose inserted into the
brake fluid is still bubbling when pressing down the pedal.
(g) Keep the free end of the hose immerged in the brake fluid to avoid air from flowing into the
system while opening the screw.
(h) While air bleeding, hammer the casting part of the vibrating brake device with a rubber hammer.
This is helpful for removing bubbles deep in the brake fluid.
(i) If air in the master cylinder is suspected, then perform air bleeding on the master cylinder first,
then the wheel cylinder or brake caliper.
(j) When releasing air from the tires, generally make sure to release air out of all the tires.
(k) To avoid the possibility of air reversely entering into the system, a bleeder hose that has a check
valve could be used.
(2) Pressure blow-off
Under the proper conditions, a pressure blow-off device can be used to release the air inside the brake system.
3. Air releasing sequence
(1) Master cylinder air bleeding
If the master cylinder does not have air bleed screws, perform the follo\
wing steps:
(a) Check the brake fluid level inside the master cylinder’s reservoir and add to it if necessary.
(b) Slowly take off the front brake pipe connector until the brake fluid flows out from the end.
(c) Reconnect the brake pipe, but do not tighten it.
(d) Slowly step down and press on the brake pedal, check if the brake fluid flowing out of the connector
contains bubbles.
(e) Tighten the pipe fitting.
(f) Have the assistant loosen the pedal, wait for 15 s.
(g) Repeat the above steps until all the air is released.
(h) Take off the rear brake pipe connector, repeat the above steps.
(2) Wheel brake air releasing
(a) Check the brake fluid level inside the master cylinder’s reservoir and add to it if necessary. During the
entire air releasing period, check repeatedly and add promptly.
(b) Connect one end of the bleeder hose with the bleed screw and the other end immerged in the brake fluid.
(c) Have the assistant step on the pedal several times, raise the pedal gradually until it cannot be stepped on
any more, then forcibly press on the pedal once more.
(d) Loosen the bleed screw, check if there are any bubbles in the brake fluid flowing out. Meanwhile, slowly
lower the pedal.
(e) When the brake pedal is close to the stroke end or the out flowing brake fluid does not have any bubbles,
tighten the bleed screw.
(f) Have the assistant release the pedal and wait for 15 s.
(g) Repeat the above steps until there are no bubbles in the flowing brake fluid when the screw is loosened.
(h) Release the air for all the wheels in turn using the same method.
(i) After releasing the air from the entire system, switch the ignition to the on position.
(j) Inspect the stroke of the brake pedal and its reaction.
(k) Inspect the lighting condition of the brake warning lamp, and repeatedly perform maintenance or air
bleeding if necessary.
( l ) Add brake fluid to the reservoir until the specified fluid level, air bleeding is complete.

4. EBD working process
The EBD comes into effect when the wheel brakes are lightly applied. The wheel speed sensor detects the speed
of the wheels, and the ECU calculates the speed. If the rear wheel's slip ratio increases, adjust the brake pressure
to maintain or reduce the rear wheel's braking force. The EBD guarantees the rear wheel's lateral force and even
brake force distribution. If the ABS fails to respond, the electronic brake distribution system can still adjust the
rear wheel's braking force to guarantee the rear wheels do not lock before the front wheels, in order to ensure
vehicle safety.
The EBD's working process for lifting and holding pressure is completely the same as it of the ABS working
process. However, the process for lowering pressure is quite different. When the rear wheel has a tendency to
lock up, the normally open valve of the rear wheel closes, the normally closed valve opens, and the rear wheel
pressure reduces. The difference with ABS is that the hydraulic pump does not operate at this time, and the brake
fluid released during depressurization is temporarily stored in the low pressure accumulator. After braking,the brake
pedal is loosened, and the brake pressure inside the pump drops to zero. Open the normally closed valve one more
time at this point. The brake fluid inside the low pressure accumulator returns to the pump by passing through the
normally closed valve and normally open valve. Empty the low pressure ac\
cumulator to prepare for the next brake.
ABS installation
1. Install the ABS controller assembly.
(a) Use three hexagon bolts for flange face (Q1840825) to
fix the ABS bracket assembly onto the vehicle body.
(b) Fix the shock pad of the ABS hydraulic pump onto the
mounting holes of the ABS bracket assembly.
(c) Insert the mount pin of the ABS controller assembly
into the shock pad holes by simply inserting the two
anchor pins into the bracket.
2. Install the ABS front wheel speed sensor with bracket
assembly.
(a) Use a hexagon head bolt, spring washer, and flat
washer subassembly to connect the sensor and the
steering knuckle.
(b) Use a hexagon head bolt and a flat washer subassembly
(M8) to connect the sensor bracket and the damper.
(c) Use a hexagon head bolt and a flat washer subassembly
(M6) to connect the sensor bracket and vehicle body.
