Air Brake vs. Oil Brake: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 26, 2024
Air brakes use compressed air for vehicle stopping power, commonly in heavy vehicles, while oil brakes, or hydraulic brakes, use fluid pressure for braking, typically in lighter vehicles.

Key Differences

Air brakes, utilizing compressed air to operate, are essential in heavy-duty vehicles like trucks and buses for effective stopping power. In contrast, oil brakes, also known as hydraulic brakes, use a fluid-filled system to transmit braking force, commonly found in cars and motorcycles.

The air brake system is known for its reliability in large vehicles, providing a failsafe mechanism where loss of air pressure results in braking engagement. Oil brakes, relying on hydraulic fluid, offer a more compact and responsive braking system suitable for smaller vehicles.
