- Brake Drum is an important component of an automobile used to
apply brake on the wheel through the brake shoes fitted inside the
Drum.
- The primary purpose of the brake drum is to absorb kinetic
energy during braking. Also, being a part of load carying member of
a vehicle, different load conditions are required to be considered
for the brakedrum analysis.
- When a driver applies the parking brake on a vehicle equipped
with rear drum brakes, it pulls cables that are attached to actuator
levers and struts inside the brake drum.
- Hydraulic pressure from the master cylinder expands the wheel
cylinder at the top of the backing plate.
- The wheel cylinder is attached to the top end of the two semi
circular brake shoes which are pressed into the inside of the brake
drum by the expansion of the wheel cylinder. Friction between the
brake shoe lining and the brake drum slows the car.
- Any time brake service is performed, all brake drums should be
inspected for the following: Excessive wear or scoring, Hot spots or
heat checks, Out-of-round, Distortion, Cracks.
- Any brake drum that is cracked must be replaced. Those that have
hot spots, distortion, or are out-ofround can cause braking problem
such as pulling, vibration, chatter, noise and pulsation.
- Many times these drums can be refinished and reused, other times
they must be replaced. Drums that exhibit minor scoring but have no
other problems can sometimes be reused without refinishing; however,
it is critical
that the diameter of a drum be measured to determine if it can be
safely refinished and reused.
- Wheels are directly mounted on the same studs as the brake drum
to stop the rotation of the wheels. Pressing the brake pedal causes
the fluid to flow from the master cylinder to each wheel cylinder.
- This causes the brake shoes to pressed against the inner surface
of the drum creating friction. The rotation of the drum stops or
slows down due to friction generated between brake drum and brake
shoes, which ultimately either reduces the speed of the vehicle or
completely stops the wheel from rotating according to the brake
application.
- Currently, China major producer of automobile brake drum factory
about 21, mainly in Shandong, Hubei and Henan and other places, and
their production capacity accounts for more than 60 national
markets, but still there are many small factories in the production
of brake drum .
- Many modern cars, e.g. the VW Touran, still come with front disc
brakes and rear drum brakes, and some sports cars still have a small
drum brake attached to the rear brakes to act as the handbrake,
although they have rear discs for the most efficient braking.
- Disc brakes are good because when they warm up, the disc gets
larger and is therefore closer to the pads, meaning you don't have
to push as hard on the pedal to get good braking.
- If you own an aircooled Volkswagen, please rest assured that if
your car came with all-round drum brakes then they are good enough
to stop it within current safety distances.
