Inspection on and adjustment of brake pedal
1. Check the pedal height as shown in the drawing to
whether it is correct,
The height from the pedal to the front floor:
Dr SF
160mm
SL SK SY SJ
(190-200)mm
2. Adjust the pedal height if necessary:
(a) Loosen the locking nuts of braking lamp switch;
(b) Loosen the braking lamp switch to the most degree.
(c) Loosen the locking nuts of drag rod;
(d) Adjust the pedal height through rotating the pedal drag
rod;
(e) Rotate the stop light switch reversibly until it contact
with the stop baffle of pedal.
(f) Screw up the two locking nuts.
(g) Check the braking lamp is lightened or not when tread
down the brake pedal.
(h) Check and adjust the pedal free stroke after adjusting the
pedal height
QKAdjust the free stroke of pedal if necessary:
(a) Loosen the locking nuts of the pedal drag rod and rotate
the pedal drag rod to adjust the pedal free stroke.
(b) Start the engine to confirm the free stroke.
(c) Check the pedal height after adjusting the pedal free
stroke. 3. Inspection on Pedal Free Stroke:
(a) Stop the engine working and tread down the brake pedal
several times until the vacuum booster is not in the stage
of vacuum.
(b) Tread down the pedal until the resistance occurs, and
measure the distance shown in the drawing.

Vacuum Booster
Inspection on Vacuum booster parts
Operation for one-way valve inspection
(Gasoline engine)
(a) Tear down the one-way valve;
(b) Check the air to see whether it flows from the vacuum
booster side toward the engine side.
(c) Check the air, change the one-way valve if the air flows
from the side of engine toward the vacuum booster.
(d) Mount the one-way valve in the right place.
(a) Tear down the one-way valve from the vacuum pipe.
(b) Check the air to see whether it flows from the side of
vacuum room to the hose.
(c) Check the air, and change the one-way valve if the air
flows to the hose to the vacuum room.

Mount of Vacuum Booster
1. Adjust the length of vacuum booster pushrod:
(a) Mount the sealing washer on the master cylinder;
(b) Put SST on the sealing washer and descend the pin rod
until it contact lightly the piston with its top;
(c) Put top of SST downward ,and mount it on the vacuum
booster.
(d) Check the clearance between the vacuum booster pushrod
and the head of pin on SST.
(e) Adjust the length of vacuum booster pushrod until the
pushrod touches the pinhead.
2. Mount the vacuum booster, sealing washer and Ushaped
clip head.
(a) Mount the vacuum booster and sealing washer.
(b) Mount the U-shaped clip head.
(c) Mount and tighten the assembling nuts of vacuum booster.
3. Connect the U-shaped clip head and the brake pedal:
Encase the U-shaped clamping pin in the hole of U-shaped clip
head and the brake pedal, and then mount the spring pin on the
U-shaped clamping pin.SST

Brief Introduction
1. Power supply system
The power supply system includes accumulator, generator and its adjustor. Generator is the main power supply; the
accumulator is the auxiliary power supply. The generator, parallel with the accumulator, is equipped with the
adjustor, which is used to maintain the voltage of generator stable when the rotating velocity and the load varies.
2. Starting System
Which includes the direct current motor, drive mechanism and control device, etc. its performance is to start the
engine.
3. Lighting system
Which includes various lighting lamps inside and outside of the body and their control device; they are used mainly
to guarantee safety driving in night.
4. Alarming System
Which includes the electric horn, flasher and various service signal indicating lamps, etc. they are mainly used to
guarantee the physical and driving safe when driving.
5. Auxiliary Electric Appliance System
It includes the electric wiper, air-conditioner, recorder and cigarette lighter, etc.

1. The codes of sockets of socket plugging element are
complied from left to right.
2. The codes of sockets of socket plugging element are
compiled from right to left.
Remark: all of plugging elements are watched from the in-
wiring direction.
3. Comparison between plug and socket plugging elements
The plug and socket plugging elements are classified accord-
ing to their in-built socket shape.
(a) All of plugging element are marked according to the
opening end and are locked at their tops.
(b) When pulling the plugging element, pull the plugging
element itself instead of wire.
Remark: before pulling the plugging element, check the
plugging element that you want to disconnect first to verify
their classifications.
English letters for wiring colors code:
B =black Bl =blue R =red Br =brown
Lg =reseda V =purple G =green O =orange
W =white Gr =gray P =pink Y =yellow
First letter stands for the basic color, while the second for the
stripe color.
