How Do You Put Air Brake Fluid in a Semi Truck?

Putting air brake fluid into a semi-truck requires following a few simple steps. This is important to keep the brakes in good condition and ensure they are functioning properly.

Air brake fluid should be changed every two years or when the brake system has been repaired or replaced. Here’s how to put air brake fluid in a semi-truck:

Step 1: Park your semi-truck on level ground in an area with good ventilation. Make sure the parking brake is engaged. Locate the air tanks and the air pressure regulator on your vehicle.

Step 2: Securely attach a hose from the air tank drain valve to an approved container for draining the old fluid. Open the drain valve and allow all of the old fluid to drain out of the tank into the container. Once it’s drained, close the drain valve and remove the hose from the tank.

Step 3: Fill an approved container with fresh air brake fluid, then attach that container to your vehicle’s air tank fill valve using a hose with a secure fitting. Open the fill valve and allow new air brake fluid to flow into your tank until it reaches its capacity level as marked on its side.

Step 4: Close both valves on your vehicle’s air tanks, then check all lines and fittings for any leaks or damage before testing your brakes by pressing down on them several times in succession until they stop completely each time.

Putting air brake fluid in a semi-truck is an easy process, but one that must be done correctly for safety reasons and proper functioning of your brakes. Make sure you use fresh, approved fluids, because any impurities can cause damage to your braking system over time if not taken care of properly.

Conclusion: Properly filling up a semi-truck with fresh air brake fluid is essential for safe operation of your vehicle, as well as keeping its brakes in good condition over time. By following these four steps, you can easily put new air brake fluids into your truck without any hassle.
