Chapter 1 Brake system

Section 1 Parameter of brake system

1. Inspection on surface of brake disc

Rubbing surface of brake disc should be flat and have no obvious dent, or replace it.

2. Inspection on thickness of brake disc

Check thickness of brake disc with caliber rule.

Standard thickness of front disc (ventilation disc) is 22mm, and using limit is 20mm; Replace it if the limit is

exceeded.

3. Inspection on throb of brake disc

Check throb quantity of terminal face of brake disc with dial gauge, and using limit of front disc is 0.03mm.

4. Inspection on thickness of brake friction wafer

Standard thickness of front brake friction wafer is 13mm and using limit is 3mm,in which remnant thickness of

thickness limit of brake pad should not less than 1mm. (Not include backboard.)

Standard thickness of friction wafer of rear brake hub is 5mm and using limit is 1mm, in which remnant

thickness of thickness limit of brake pad should not less than 1mm.

5. Remark

Please inspect thickness of outer brake friction wafer via hole of wheel spoke before disassemble the wheel,

or check it after disassembled the wheel.

Important prompt:
² After replaced friction wafer or brake disc, tread the brake for some times to make brake friction wafer fit

up brake disc and ensure safety!

² After replaced brake friction wafer, please check if liquor level of brake fluid is between MIN and MAX.

Section 2 Disassembly and assembly of front wheel brake

1. Assembly diagram of front wheel brake

2. Preparation of disassembly and assembly

Tools: Ratchet wheel, ratchet pole, 11#, 17#, 19#, 30# sleeve, 14#, 17#, 19# box wrench, jaw vice, torque wrench.

Supplementary materials: Brake fluid

3. Precautions

3.1

Please wear necessary appliances for labor protection to avoid of accident.

3.2

Brake fluid is poisonous liquid, please clean with clean water if contacts it with skin or eye in careless, and

take medical treatment in time if it is necessary.

3.3

Load dumped brake fluid into container. Do not empty it into water drain or pile it up with consumption

residues.

3.4

Do not tread the brake pedal or move the vehicle during disassembly and assembly.

3.5

Never make friction wafer or friction disk contact with material of fat liquor, to avoid of reducing brake

performance.

4. Disassembling step

4.1

Loosen drive nut of front wheel with torque wrench

and 30# sleeve, but disassembling it completely is not

necessary.

Moment of force: 265±5 N.m
