Curious as to how air brakes work? Well, it all starts with your air compressor. Every heavy-duty truck that’s equipped with air suspension will have a large air compressor mounted to the back of its engine. This air compressor is tasked with filling several air tanks with compressed air. One important thing to note is that this compressed air is run through a dryer. This removes all of the moisture from the air, for otherwise, it could freeze within your airlines.
So now you’ve got full compressed air tanks. What’s next? When you press down on the brake pedal in your heavy-duty truck, you’re sending compressed air to the drum brake assemblies on each wheel. This stream of compressed air will activate each service chamber, which in turn sets your pushrods and q-cams in motion. Your pushrods will move forward and rotate your q-cam, which in turn pushes your brake shoes outwards. Your brake pads are mounted on the outside of these brake shoes and, as such, are compressed against your brake drums. This brings your truck to a stop!
Brake adjusters take up the slack within your drum brake system to make up for inevitable brake pad wear. Taking up slack is a super important task, for if your pushrods have to travel far before activating your brakes, your overall performance will almost certainly drop. Although brake adjusters are automatic, they can malfunction over time due to wear and tear. If you think your brake adjusters are not functioning how they should be, give us a call and we’ll book you in for service.
