  • 1. Function
    Our truck brake padsis an ideal replacement of the metallic (gray cast iron) brake block. truck brake padsfeatures motion to the wheel and well fitness between the truck brake padsand truck brake padsshoe

    2. Operational heat
    Our truck brake padswon't melt or burn and continues to work at a temperature of 250

    It may burn but causes no flame at a temperature of ≥ 400

    3. Materials
    A. The materials of truck brake padsconsist of 3 main substances including reinforcing fiber, organic/inorganic filler and resin bound.
    B. It has a high level of uniformity.
    C. It can be separated from the backing plate.
    D. It contains no asbestos, lead, zinc or other mixtures.
    E. It also contains no toxic materials.
    F. The hardness of the material is lower than the wheel's.
    G. It causes no strong smell in friction.

    4. Backing plate
    Backing plate for a trains' truck brake padsmust meet the following criteria. Firstly, it is made of ST-41 steel plate, and is constructed to transmit the braking force to the composite material. Secondly, there should be a binding structure between the composite material and backing plate, thus forming into a integrated unit and ensuring sufficient bending strength and stiffness.

    5. Performance
    A. Excessive wear won't be caused on the surface of the wheel and the truck brake pads.
    B. The truck brake padswill not cause the wheel porous or cracked.
    C. It won't stick at the wheel during braking therefore won't cause uneven wheel surface.
    D. It won't cause wheel slipping during full braking in wet conditions.

    6. Test procedure
    A. Vernier caliper or other methods are used to test the dimension of the brake block.
    B. Laboratory test
    Specific gravity test: standard ASTM D 792 or equivalent method
    Coefficient of friction test: Standard ASTM D 1894 or equivalent method
    Hardness test: standard ASTM D 785 or equivalent method
    Shear resistance test: standard ASTM D 732 or equivalent method
    Press test: Standard ASTM D 695 or equivalent method
    Bending test: Standard ASTM D 790 or equivalent method
    Thermal properties test: standard ASTM D 177 or equivalent method


  • Characteristic Unit Value Testing Method
    Specific Gravity gr/cm3 1,7 – 2,4 ASTM D792
    Coefficient of Friction   0,14 – 0,22 ASTM D1894
    Hardness HRR 70 – 105 ASTM D785
    Crush Strength N/cm2 Minimum 2500 ASTM D695
    Bending Strength N/cm2 2400 – 4000 ASTM D790
    Tensile Strength N/cm2 480 – 1500 ASTM D3039
    Shear Strength N/cm2 1500 - 3500 ASTM D732
    Heat Resistance: 250ºC
    Result: Does not melt and burn for continuous use.
    Result: May burn but does not cause the flame.
