Instruction and Operation
Braking Test
Warnings: During checking the brake, the
smog released by hot braking can be avoided.
See Safety and Health Precautions.
Avoid the check of the brake on the road with many
vehicles, as that may cause inconvenience or danger
for others.
Warnings: The braking test including the
heavy-trodden braking shall be not performed
on new brake shoe plate/brake disc or the
friction disc/brake drum, unless the components
have been worn in, because the new braking
friction components can not perform the
complete functions before being worn in.
Slightly step or heavily step on the braking pedal
under the condition of various vehicle speeds of
normal operation at each gear position, so as to
check the brake.
Slide the vehicle and pay attention to the tendency
of vehicle derivation or the phenomenon of viscous
braking.
After the vehicle (stop of non-emergency braking)
is stopped, check the braking temperature carefully.
If the brake disc is extremely hot or the brake disc
is hotter than other brake discs, it is indicated that
the phenomenon of viscous braking exists.
After the test is finished, check:
– Check whether the leakage of engine oil,
coolant, hydraulic pressure, air and fuel exists.
–
The abnormal high temperature of any
rotating components or assemblies, such as
wheel hubs, speed change gear, axle, etc. may
show excessively tight assembly or deficient
lubrication.
