Braking systems are critical for vehicle safety, and two primary types are widely used in automobiles: disc brakes and drum brakes. Each type has distinct working mechanisms, advantages, and common applications.
How They Work:
Disc brakes use a caliper to press brake pads against a rotating metal disc (rotor) to slow down or stop the vehicle.
Advantages:
Better heat dissipation: Effective in preventing overheating.
Superior stopping power: Ideal for high-speed braking.
Less prone to brake fade: Perform reliably under heavy braking conditions.
Consistent performance: Provides smooth and predictable braking.
Commonly Found:
Front wheels of most vehicles.
All four wheels of high-performance cars.
How They Work:
Drum brakes use brake shoes that press outward against the inside of a metal drum to create friction and slow the vehicle.
Advantages:
Cost-effective: Cheaper to manufacture and repair.
Durable: Generally lasts longer in less demanding braking conditions.
Multi-purpose: Often doubles as a parking brake.
Commonly Found:
Rear wheels of many vehicles, especially older or budget models.
