Brake
system
Service brake type
The service brake system adopts a hydraulic vacuum power-assisted type.
The front/rear brakes are disc and drum brakes respectively. The front brake
uses a ventilated disc, and the brake pedal is a suspended pedal with vacuum
booster. Brake line is in a dual-circuit diagonal (X type) arrangement,
adopting a ABS + EBD anti-lock and braking force distribution system.
Service brake booster
and master cylinder
Single stage Φ9inch vacuum booster, series dual-chamber brake master
cylinder, cylinder bore Φ22.22 mm, stroke 32 mm
Brake reservoirShares with the clutch master cylinder reservoir and installed with a brake
fluid level alarm.
Brake pedal strokeFree play: 6-9 mm, working stroke: 37-40 mm.
Brake pedal pressure<380 N (no load) <480 N (full load)
Parking brake
The parking brake system uses a mechanical remote ratchet cable control
mechanism to control the rear wheel drum brake. Brake lever's functional
stroke is 5-8 gearteeth.

placement
Remark: When applying the brake while driving, if the front
tires makes a continuous screeching sound, inspect the inner
and outer brake pad and friction limit alarm plate. If there
are traces of rubbing from the brake disc on the alarm plate,
the inner and outer brake pad assembly should be replaced.
1. Remove the front wheel.
2. Inspect the inner and outer brake pad's friction material
thickness.
By looking through the caliper's observation ports, inspect
the inner and outer brake pad friction material thickness. If it
is no longer within the specified range, it should be replaced.

(a) Install inner shim A and B onto the inner brake disc.
(b) Install outer shim A and B onto the outer brake disc.
(c) Install the inner and outer brake pad assembly with
inner muffler plate subassembly onto the caliper frame.
Make the inner brake pad assembly with inner muffler
plate subassembly and alarm plate rest close to the
brake caliper's inner side.
Caution: For the inner and outer brake pad assembly,
the working surface of the brake disc must not have
any grease, oil or paint pollution.

from the reservoir).
(e) Press in the piston with SST.
9. Install the caliper assembly.
Loosen the rope, remove the caliper assembly, and tighten
the hexagon bolt for flange face.
Tightening torque: 30±5 N·m
Remark: Replace one wheel's brake pad at a time, in order to
avoid the other wheel's piston from springing out.
10. Install the front wheel.
Tightening torque for the wheel retaining nut: 100±5 N·m

Front brake caliper assembly installation
1. Preparations
Make sure all parts are clean and free of foreign materials
before installation.When installing, apply an appropriate
amount of rubber grease to the guide pin and piston's
working surface, as well as the rectangular sealing ring and
the piston protective cover's working surface.
2. Install the rectangular sealing ring to the caliper.
(a) Screw the bleed screw into the caliper's vent holes.
Tightening torque: 10±2 N·m
(b) After applying an appropriate amount of rubber grease
on the rectangular sealing ring's working surface, install
them into the caliper's seal groove.
3. Install the piston with piston dust cover on the caliper.
(a) Place the piston dust cover on the piston.
(b) Stretch the piston dust cover, until its card holder
exposes the bottom of the piston. Use tools (for
example, about Ф2 mm of iron wire) to assist by
stuffing the card holder into the cylinder bore card
holder's groove.
Caution: The tools being used should not be sharp, as
to avoid tearing the dust cover.
(c) Then manually press the piston into the bottom of the
cylinder bore.
4. Install the guide pin and guide pin dust cover onto the
caliper frame.
(a) Install the guide pin dust cover onto the guide pin.
(b) Screw the guide pin into the caliper frame.
Caution: Do not damage the guide pin dust cover.
5. Install an inner and outer brake pad assembly and
inner and outer muffler plate subassembly.
6. Install the brake block yoke spring plate as well as the
inner and outer brake pad assembly and inner and
outer muffler plate subassembly on the caliper frame.

Functional description and display program
1. This system will be activated within the first second after engaging the reverse gear. There will be two
beeps indicating the system is working properly.
2. After the self-check, it will start its normal detection mode. The relationship between the obstacle
distance and the alarm frequency is as follows:
A Zone: When it is a long sounding alarm, the obstacle is within the distance of (0-40±4) cm.
B Zone: When the alarm frequency is an 8 Hz continuous sound, the obstacle is within the distance of
(40±4-90±4) cm.
C Zone: When the alarm frequency is a 4 Hz intermittent sound, the obstacle is within the distance of (90±4-
150±4) cm.
Areas of importance
1. When placed near a car equipped with the same system or a similar system (having been activated)
offered by other suppliers, though this system may receive interference, i\
t can still operate normally.
2. When the relative rate of travel between the obstacle and the car is lower than 1 m/s, this system will
operate as normal. When reverse speed is accelerated, the sensing accuracy of the reverse system
may decrease. A low speed of 6 km/h is suggested.
3. When it is a long sounding alarm, please stop the car at once, because there may be an obstacle
within 40cm.
4. The inductor precision level is high. It will be very difficult to return it to normal after opening the inner
portion.
5. The reflected signal may not be received due to the location, angle, size, or material of the object.
Furthermore, the reflected signal in a complex environment may not be ac\
curate.
System malfunction causes and solutions
1. A lack of power or a low supply voltage may lead to the abnormal operation of the reverse sensor
system. Under such circumstances, check whether the supply battery voltage is normal, or whether
the ignition switch connector and other connections are accurately place\
d.
2. If the power supply is on, irregular system operation may be caused by the incorrect position of the
socket. Under such circumstances, correctly re-place all the sockets.
3. A long sounding alarm from the buzzer may be caused by the inductor coming off, incorrect installa-
tion, damage to the inductor, or detecting the car or ground. Under such circumstances, please repair
or replace the sensor.
4. Incorrect indication of an obstacle's distance may be caused by abnormal battery voltage, inaccurate
socket positioning, or inductor connection damage. At this time, check whether the battery voltage
is normal, and whether the inductor connection is connected to the exhaust pipe and muffler. It is
suggested that the system be turned off and all the sockets be correctly placed.
