100000Km NAO Material Drum Brake Linings For Commerical Vehicles
What is commercial vehicles?
In the United States a vehicle is designated “commercial” when it
is titled or registered to a company. This is a broad definition,
as commercial vehicles may be fleet vehicles, company cars, or
other vehicles used for business. Vehicles that are designed to
carry more than 15 passengers are considered a commercial vehicle.
Variations may exist from state-to-state on which "commercial
vehicles" are prohibited on certain routes and lanes and between
homeowner associations, which may employ broader definitions than
their municipalities with regard to their own parking restrictions.

A commercial vehicle is any type of motor vehicle used for
transporting goods or paying passengers. The European Union defines
a "commercial motor vehicle" as any motorized road vehicle, that by
its type of construction and equipment is designed for, and capable
of transporting, whether for payment or not:
(1) more than nine persons, including the driver;
(2) goods and "standard fuel tanks". This means the tanks
permanently fixed by the manufacturer to all motor vehicles of the
same type as the vehicle in question and whose permanent fitting
lets fuel be used directly, both for propulsion and, where
appropriate, to power a refrigeration system. Gas tanks fitted to
motor vehicles for the direct use of diesel as a fuel are
considered standard fuel tanks.
What is commercial vehicles brake ?
There are two types of brakes of commercial vehicles:
1) Drum Brakes
How drum brakes work ?
When the driver steps on the brake pedal, the power is amplified by
the brake booster (servo system) and changed into hydraulic
pressure (oil-pressure) by the master cylinder. The pressure
reaches the brakes on the wheels via tubing filled with brake oil
(brake fluid). The delivered pressure pushes the pistons on the
brakes of the four wheels. The pistons press the brake linings,
which are friction materials, against the inside surfaces of the
brake drums which rotate with the wheels. The linings are pressed
on the rotating drums, which in turn decelerate the wheels, thereby
slowing down and stopping the vehicle.
Inspection Item | Test Result |
NormalTemperature Friction Coefficient(100-150ºC) | 0.42±0.02 |
Hot Friction Coefficient(250ºC-300ºC) | 0.42±0.01 |
Wear Rate(×10-7m3/Nm150ºC) | 0.26-0.53 |
Density(g/cm3) | 2.22 |
Impact Force(J/cm2) | 0.46 |
2) Disc Brakes
How disc brakes work ?
The brake rotor (disc) which rotates with the wheel, is clamped by
brake pads (friction material) fitted to the caliper from both
sides with pressure from the piston(s) (pressure mechanism) and
decelerates the disc rotation, thereby slowing down and stopping
the vehicle.
