If you inspect older models of cars, you will notice that they have a different braking system as compared to modern vehicles. Most of the older sets of wheels use drum brakes, which have a set of shoes or pads that press outward against a rotating cylinder part called the brake drum , creating friction and allowing a car to halt. Others may argue that these stopping systems are outdated, but some disagree saying they still serve their purpose, which is to help a vehicle stop. The maintenance is easier. Drum brakes have an all-in-one, enclosed design with most components being held in place by spring tension.

How Drum Brakes Work?- Easiest Explanation Ever

Although disc brakes appear to have won the popularity contest in motor vehicles generally, drum brake technology is hanging on in certain CV sectors. Buyers face a trade-off between capital cost and weight. By Chris Tindall. All over the world, countless numbers of disc brakes are specified in a wide range of vehicles. Unlike them, however, the UK market continues to hang on to drum brakes in some applications. Clearly, both have their advantages and disadvantages. According to Lumag, drum brakes, owing to their compact structure and installation in an enclosed operating space, reduce penetration of contaminants that usually lower the friction coefficient.

6 Advantages and Disadvantages of Drum Brakes

With the function of automatic brake , the brake system can use lower oil pressure, or use a brake drum with a diameter much smaller than the brake disc. The installationof the hand brake mechanism is easy. Some rear-wheel-drive disc brakes will have drum brakes mounted on the center of the brake. The processing and composition of parts is relatively simple, but there are relatively low manufacturing costs. The brake drum of the drum brake will increase in diameter after being heated, which will increase the stroke of pressing the brake pedal and cause the brake reaction to be less than expected.

If someone ask you a question that can you drive your vehicle without brakes? Than what will your answer, obviously No. Driving a vehicle without brakes is impossible. Brakes are crucial for stopping a vehicle and drive safely on the road. Use of proper braking system enhances handling of the vehicle to a greater extent. In modern vehicle the drum brakes are mostly installed at rear wheels. There are different types of brakes available in the market.

How Drum Brake Works? It’s Advantages & Disadvantages

In our daily life, we see the braking effect everywhere, like bicycle, motorcycle, car, bus, train, and more. The list is quite long. So to get the breaking effect we need to have some component which produces the effect, is not it? So that particular component which generates the braking effect is called Breaking System. A Branking system can be made of sevaral components, and have different types.

Disk Brake Maintenance, Working, Pros & Cons (Part 4)

Brakes: Drum vs. Disc

Brake technology, just like suspension technology and fuel-system technology, has come a long way in recent years. What began in the '60s as a serious attempt to provide adequate braking for performance cars has ended in an industry where brakes range from supremely adequate to downright phenomenal. The introduction of components like carbon fiber, sintered metal and lightweight steel, along with the adoption of ABS, have all contributed to reduced stopping distances and generally safer vehicles though ABS continues to provide controversy. One of the first steps taken to improve braking came in the early '70s when manufacturers, on a widespread scale, switched from drum to disc brakes. Since the majority of a vehicle's stopping power is contained in the front wheels, only the front brakes were upgraded to disc during much of this period.

A drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating cylinder-shaped part called a brake drum. The term drum brake usually means a brake in which shoes press on the inner surface of the drum. When shoes press on the outside of the drum, it is usually called a clasp brake. Where the drum is pinched between two shoes, similar to a conventional disc brake , it is sometimes called a pinch drum brake , though such brakes are relatively rare. A related type called a band brake uses a flexible belt or "band" wrapping around the outside of a drum. The modern automobile drum brake was first used in a car made by Maybach in , although the principle was only later patented in by Louis Renault. He used woven asbestos lining for the drum brake lining, as no alternative dissipated heat like the asbestos lining, though Maybach had used a less sophisticated drum brake.

Two-wheelers such as scooters , commuter bikes , three-wheelers including auto-rickshaws widely use the Drum Brake system for braking. This type of brake got its name from the drum structure of cylindrical-shape. Hence, the name. How does Drum Brake work? When you press the brake pedal, the cam turns. Thus, it causes the brake shoes to expand outwards and rub against the drum. The friction between the brake linings and the drum causes the drum to stop rotating; thereby stopping the wheel.


  • Here are some advantages that drum brakes have over disc brakes: Drum brakes can provide more braking force than an equal diameter disc brake. Drum brakes last longer because drum brakes have increased friction contact area than a disc. Drum brakes are cheaper to manufacture than disc brakes. Cumitalptor - 09.06.2021 at 16:02
