Disc Brake Assembly

A disc brake assembly is a modern vehicular braking system. It consists of a brake rotor attached to the wheel and calipers with brake pads. When the brake pedal is pressed, calipers squeeze the pads against the rotor, generating friction that slows down or stops the vehicle efficiently and quickly.

Types of Disc Brake Caliper Assembly

Benefits of Disc Brake Cylinder Assembly


Drum brakes are generally less expensive to manufacture and maintain, making them a cost-effective choice, especially for rear-wheel applications in budget-conscious vehicles.

Parking Brake Function: 

Drum brakes often serve as parking brakes due to their self-locking mechanism, providing reliable parking security.

Less Susceptible to Environmental Factors: 

Enclosed drum brake design is less prone to water and debris ingress, making them suitable for certain off-road and harsh environments.

Smooth Braking Engagement: 

Drum brakes offer smoother engagement due to their gradual application, making them suitable for certain driving conditions and passenger comfort.

Differences Between Drum Brake Assembly And Disc Brake Assembly


Drum brakes use brake shoes expanding against a drum, while caliper assy disc brake employ calipers squeezing brake pads onto a rotating disc.

Friction Area:

Drum brake assembly has internal friction surfaces, while disc brake rotor and hub assembly have external rotors with larger friction areas for improved heat dissipation.

Heat Dissipation:

Disc rotor assembly dissipates heat more effectively, reducing the risk of brake fade during prolonged or heavy use.


Disc brake assembly parts are generally easier to inspect and maintain, whereas drum brakes can be more complex to adjust and overhaul.


Disk brake assembly has natural air cooling due to its exposed design, while drum brakes are less efficient at dissipating heat.


Components of disk brake caliper assembly are lighter, contributing to reduced unsprung weight and improved handling compared to drum brakes.

Emergency Brake:

Drum brakes often serve as parking/emergency brakes due to their self-locking mechanism, while disc brakes require additional mechanisms.


Disc brakes are more common in front-wheel-drive vehicles and high-performance applications, while drum brakes are still used in some rear-wheel-drive and light-duty applications.
