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 SF160mm
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.

Operation test of vacuum booster
Remark: check the operation of vacuum booster with the
vacuum booster tester if workable.
1.Operation inspection
(a) Before starting the engine, tread down the brake pedal
several times, and check the pedal reservation distance to
ensure there is no change occurs.
(b) Tread down the brake pedal and start the engine. If the
treaded pedals continue to move downward, which means
the operation is normal.
1. Inspection on Air-tight
(a) Start the engine for 1-2 min and then turn it off. Then
tread down the brake pedal slowly for several times, if the
pedal move downward continuously in the first, but
return gradually in the second or third time, which means
the vacuum booster has a good air-tight.
(b) Tread down the brake pedal when the engine is working,
then stop the engine, but tread the pedal down. If the
reservation distance doesnít change within the 30 seconds,
which shows the air tight of vacuum booster is good.
Air-bleeding of braking system
Remark: air-bleeding is required if any operation for braking
system is conducted or the pipe line is doubted to have air.
1. Fill the oil cup with the brake liquid
Check the liquid level of oil cup after the air in each wheel
brake pump is exhausted. If necessary, add the brake liquid.
2. Connect the vinyl resin pipe with the vent screws.
Insert the other end of pipe into the container with half brake
liquid.
Remark: the air-bleeding shall begin from the longest pipe line
when the wheel-brake cylinder is exhausting the air.
3. Air exhaust of the pipe line in braking system
(a) Tread down brake pedal slowly several times.
(b) Loosen the vent screws until the brake liquid flows out
while letting the assistant tread down the pedal. Then
screw up the vent screws.
(c) Repeat this approach until there is no air in the liquid.
4. Repeat the approach for the wheel-brake cylinder.
