Well, lighter types of vehicles such as cars use hydraulic brakes , while Air brakes are their alternative when it comes to heavy vehicles such as trucks.
You probably know all this, but let me repeat it! In order to stop the car, the Hydraulic brakes are using a hydraulic fluid to transfer pressure from the brake pedal to the brake shoe.
On the other side, the large multi-trailer vehicles use Air brakes, and have quite few advantages in their favor, including:
- The brake system can never run out of its operating fluid (because the supply of air is unlimited). The hydraulic brakes can any time run out of operating fluid and result in brake failure.
- It is much easier to attach and detach airline couplings then hydraulic lines. You don’t have to worry about letting air into the hydraulic fluid. Furthermore, you don’t need special trained personnel, to attach and remove the circuits of trailers.
