Inspection and Adjustment of Clutch Pedal, Air Exhausting of Clutch
Air-exhausting of clutch
Remark: in case operation needs to be conducted for the clutch
system or if there is air in clutch, exhaust the air.
Notice : Do not stain the painted surface with brake liquid,
if any brake liquid is left, wash it away immediately.
1.
Fill the brake liquid into the oil cup of clutch master cylinder;
The oil cup of master cylinder shall often be checked and, if
necessary, added with brake liquid.
2.
Connect the ethene resin pipe to the air-exhausting valve.
Insert the other end of the pipe into the container, half of which
is filled with brake liquid.
3. Air-exhausting in clutch system
a) Move the clutch pedal up and down slowly for several times.
b) Loosen the air-exhausting valve when pressing the pedal
increasingly until there is brake liquid overflowing, then
tighten the air-exhausting valve.
c)
Repeat this operation until the bubble in brake liquid disappears.
Inspection on and adjustment
of clutch pedal
1. Check whether the pedal height is correct
Pedal height that begins from front wall board:
Dr SF
(165
5)mm
SL SK SY SJ
(190-200)mm
2. Adjust the pedal height where necessary
Loosen the locking nut and screw off the adjusting bolts until
the pedal height is correct. Then screw up the locking nut.
Pedal free stroke
3. Check whether the pedal free stroke is correct
Press the pedal lightly until the resistance generated by clutch
occurs.
pedal free stroke: (5-15)mm
4. Adjust the pedal free stroke where necessary;
a) Loosen the locking nut and rotate the push-rod until the
stroke is correct;
b) Screw up the locking nuts;
c) Check the pedal height after the adjustment of pedal free
stroke.

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
