1. Assemble the wheel-brake cylinder:
(a) Coat moderate lithium soap base glycol grease on the
piston cup.
(b) Assembly the wheel-brake cylinder
Mount the two piston cups on two pistons
Mount the two dust cover on two pistons.
Encase the spring and the two pistons in the wheel
cylinder body.
Remark: assembly correctly according to the direction shown
in the drawing.
2. Mount the wheel-brake cylinder:
(a) Mount the wheel-brake cylinder on the rear bottom plate
with two bolts.

3. Coat the lithium base grease on the following parts:
(a) Hex convex platform where the bottom plate contacts
with the brake shoe.
(b) Two ends of support brocks
(c) Contact position where the piston and the shoe rib.
Remark: Do not pollute the friction pads. Braking SystemRear Brake (SF)

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;

(b) Tear down the mounting bolts of valve bracket, and load
sensing proportion valve cluster.
Mount of Load Sensing Proportion Valve
1. Mount the load sensing proportion valve cluster on the
frame.
2. Connect the claming head II with the bracket:
(a) Mount the claming head on the load inductive spring;
(b) Adjust the spacing A.
Initial adjustment: 78 mm;
(c) Mount the claming head II on the claming head bracket
3. Connect the brake pipeline;
Connect the brake pipeline with SST.

4. Adjust the rear shaft load
5. Adjust the valve:
(a) When drag downward the load inductive spring, the
valve piston shall move downward smoothly.
(b) When mount the valve body, the valve piston shall touch
the load inductive sensing spring lightly.
(c) Screw up the mounting nuts of valve body.
