(c) Self adjusting screw arbor thread;
(d) Contact position where the self-adjusting screw sleeve
and the brake shoe.
4. Mount the parking brake lever and the toggle plate
(a) Mount the parking brake lever and lock it with a new pin.
(b) Mount the toggle plate and a new open retainer ring.
5. Mount the adjuster on the rear brake shoe:
(a) Mount the adjuster;
(b) Mount the clearance-adjusting spring;
6. Mount the rear brake shoe:
(a) Mount the brake bracing wire on the parking brake lever;
(b) Mount the tension spring on the rear brake shoe;
(c) Encase the rear brake shoe in such way that the end shoe
is inserted in the wheel-brake cylinder.
(d) Mount the brake shoe pressure spring, pressure spring
cap and the claming pin.
Notice: Do not let the oil or lubricant touch the brake
shoe. Braking System

7.Mount the front brake shoe:
(a) Mount the lower tension spring between the front shoe
and the back shoe.
(b) Mount the front brake shoe in such manner that the end
shoe is inserted in the wheel-brake cylinder, and mount
correctly the adjuster.
(c) Mount the pressure spring, pressure spring cap and
claming pin.
Notice: Do not let the oil or lubricant touch the brake
shoe.
(d) Mount the upper tension spring.
8. Check the operation of self-adjusting mechanism.
(a)Move the parking brake lever of rear brake shoe forward
and backward as shown in the drawing, check the self-
adjusting screw arbor to see whether it can rotate or not,
if not, check the rear brake to see which part has problem.
(b) Adjust the adjuster length and shorten it as can as possible.
(c) Mount the brake drum.
(d) Drag the parking brake lever to the max distance until no
quack-quack is heard. Braking System

9. Check the clearance between the brake shoe and the
brake drum:
(a) Tear down the brake drum.
(b) Measure the inner diameter of brake drum and the outer
diameter of brake shoe, then Check the difference of the
two diameters to see whether it falls within the standard
clearance range.
Shoe clearance: 0.6mm
If it is not correct, check the parking braking system.
10. Mount the brake drum and rear wheel;

On-vehicle Inspection
Steering wheel play
1.SR-18Check to see whether the steering wheel play is
correct;
Park the vehicle stably and align the tires in correct direction,
press the steering wheel with finger and swing it in left and
right direction. The play should not exceed the max play.
(Max play)
6
(Dr SF)
If the play is nor correct, adjust or repair the steering wheel as
requirement.
2. Adjust the steering wheel play:
(a) Align the wheel forward precisely;
(b) Loosen the locking nuts of steering gear;
(c) Rotate the adjusting screws of steering gear clockwise to
reduce the steering wheel play, while contrarotate the
adjusting screws to increase the steering wheel play.
Remark: screw the adjusting screws and enlarge the play a
little each time to check the adjusted play.
3. Check to see whether there is steering inconvenience
Rotate the steering wheel by half round in right and left
direction to check whether the play is correct, and whether the
wheel runs smoothly or any seize-up in its running.
4. Fix the adjusting screws and fasten the adjustable nut.
Oil level height
Check the oil level height in the steering gear housing.
Oil level height: flush with the filler opening.
If there oil is insufficient, add the gear oil and check to see
whether there is oil leakage.
