📌 Everything You Need to Know About Drum, Disc, Air, and Other Brakes:
Brakes are essential safety components in vehicles, designed to slow down or stop motion. Here are the main types of brakes and how they work:
1. Drum Brakes:
Drum brakes use brake shoes that press outward against a rotating drum attached to the wheel. When you apply the brake pedal, hydraulic pressure forces the shoes against the drum, creating friction. They’re common in older vehicles and on rear wheels.
2. Disc Brakes:
Disc brakes are more modern and widely used. They consist of a brake disc (rotor) and a caliper with brake pads. When the brake pedal is pressed, the pads clamp onto the spinning disc, slowing the wheel. They offer better heat dissipation and stopping power than drum brakes.
3. Electric Brakes:
Electric brakes are commonly found in trailers. When the driver brakes, an electrical signal activates a magnet inside the brake assembly, creating friction with the drum to stop the wheel. These brakes rely on a controller inside the towing vehicle.
4. Air Brakes:
Mostly used in heavy vehicles like trucks and buses, air brakes use compressed air to activate brake pads or shoes. When the pedal is pressed, air pressure moves a piston or diaphragm to apply braking force. They’re reliable and powerful but require regular maintenance.
5. Hydraulic Brakes:
Hydraulic brakes use brake fluid to transfer force. Pressing the brake pedal pushes fluid through brake lines to calipers or wheel cylinders, applying the brakes. They’re common in passenger vehicles and provide smooth, responsive braking.
6. Electromagnetic Brakes:
These brakes use magnetic force to slow or stop motion, often without physical contact. They're used in electric trains, industrial machines, and hybrid/electric vehicles for regenerative braking.
