There is such noise as
continuous screaming, quack-

Notice: the braking materials
may generate the natural noise
and heat during friction, and
thus emit the energy. Therefore,
it is normal to have the
screaming noise. These
phenomena will be more serious
under the condition of frigidity,
torridity, and over humidity,
snowing and mud. the
screaming noise occurring
occasionally will not lead the
fatal brake trouble nor reduce
the effective properties of the
brake.The brake drum, brake liner, liner or brake pad is worn
or scraped
The brake liner or brake pad is dirty or with oil stain or
polished.
The brake liner or brake pad is improperly used.
The brake pedal or vacuum booster drag rod is unsuitably
adjusted.
(disc type brake)
The brake pad silent pad is loss or damaged;
The brake pad is worn to the degree that the abrasion-
indicating lamp of brake pad has friction with the rotator.
There is burr or rust on the brake caliper.
