FAQ

What is a disc brake?

A disc brake is a braking system that mainly consists of a brake disc, the rotor and brake pads. When the brake is applied, the brake pads are held in place by a brake caliper hydraulic or mechanical pressed against the rotating disk. This friction slows down the rotation of the disc and therefore the wheel or shaft on which it is mounted.

What does the disc brake do?

The disc brake is designed to slow or stop a vehicle or machine by Friction on the brake discs exercises. This is done by pressing brake pads hydraulically or mechanically against the rotating disc using a brake caliper. The resulting friction between the brake pads and the disc creates a braking force that slows down the rotation of the disc and thus the wheel or shaft. It is particularly effective in dissipating heat and thus enables constant braking performance even under difficult conditions.

What is the advantage of disc brakes?

The main advantage of disc brakes is their high braking performance and reliability. They offer better heat dissipation compared to other braking systems, such as drum brakes, resulting in consistent braking performance even under demanding conditions. This reduces the risk of brake fade, where braking efficiency decreases due to overheating. Disc brakes also respond faster and offer more precise control, increasing safety. Their design allows for easy maintenance and inspection of the brake pads. These properties make disc brakes particularly suitable for vehicles and machines that place high demands on braking performance.

What are the disadvantages of disc brakes?

Despite its many advantages, disc brakes also have some disadvantages: Disc brakes are usually more expensive to produce and maintenance as drum brakes. Due to their open design, disc brakes are more susceptible to contamination and corrosion, which can affect braking performance. In addition, disc brakes are often heavier than drum brakes, which can be a disadvantage in certain applications, particularly in aviation or light vehicles. Disc brake design can be more complex. This makes repairs and maintenance difficult.

What are the advantages and disadvantages of the drum brake?

The drum brake is cost-effective in manufacturing and maintenance as disc brakes. It offers natural self-reinforcement of the braking process, which requires less pedal force. The closed design protects the brake shoes from dirt and water. The disadvantage is that drum brakes are more prone to overheating and loss of performance (brake fading) under heavy use. It is more difficult to maintain and inspect than disc brakes. They are also typically heavier, which increases the unsprung mass of the vehicle.

Which is better: disc brake or drum brake?

The Main difference The difference between disc and drum brakes lies in their design and functionality. Disc brakes use a flat disc and brake pads, while drum brakes use a rotating drum and internal brake shoes. The “better” brake depends on the application: disc brakes are generally better for high performance and safety requirements, while drum brakes may be sufficient for less demanding applications.
