Pontiac Brake Drum
Pontiac brake drum is usually found on the rear wheel of the Pontiac vehicle.
It is the circular metal component of the drum brake system that rotates along
with the wheel and uses a set of brake shoes that are fixed in a position to stop
its motion. These brake shoes forcedly expand with the use of the hydraulic force
given by the fluid from the master caliper. Basically, the Pontiac brake drum is a brake system in which the friction is caused by the brake shoes that presses
against the inner surface of the drum.
Since the brake drum is connected to the rotating wheel, we can say that the
speed of the drum is directly proportional to the speed of the wheel. If this
is the case, can you imagine how much friction and heat is generated on the braking
process just to stop this kind of power?
Most of the Pontiac vehicles use a brake drum on its rear wheel and disc brakes
on the front. Typically, Pontiac brake drum has more components than the disc
brake and is hard to replace or serviced. However, it is less expensive because
each part of the drum brake system is not complicated as the disk brake system.
The inner surface of the Pontiac brake drum is usually made from the same material
used on the surface of the brake rotor. This means that it is also subjected to
wear and tear especially when the brake shoes being used are already worn out.
Even if this system is difficult to service, regular inspection on the condition
of the Pontiac brake drum is vital to ensure that the braking capability is not
lessened and the safety of the occupants is ensured.
