The Automatic Slack Adjuster (ASA) is a vital part of the foundation brake acting as a lever, forming the connection between the actuator & the camshaft. When the brake is applied the actuator moves the ASA forward. The worm wheel rotates the camshaft, in turn moving the brake lining toward the brake drum & diss-engages when it reaches the drum. When the brake is released the reacting force drops & the ASA mechanism re-engages. If excess clearance (wear) is in the system, the worm wheel in the mechanism will not return to its original position - it will have indexed.

Brake chambers are used on truck and trailer air brake systems, located at each wheel, where compressed air is converted into a mechanical force used to apply the brakes and stop the vehicle. They are also designed to apply the the brakes automatically in the event that there is a loss of system air pressure. This happens because the air pressure holding back the heavy parking/emergency spring dissipates allowing the spring to extend the pushrod which in turn applies the brake. There are designs to cover Cam Brake and also Disc Brake applications, along with different sizes and strokes. The most common strokes are standard and long stroke.

ECAS is Electronically Controlled Air Suspension. Electronic control of the suspension guarantees optimum driving comfort and a consistent vehicle set-up based on speed, load and type of road. It also acts on braking pressure, which is proportional to the load on the axles. ILAS controls the lifting of one or more axles by sensing a load through the primary air suspension.

The compressor builds up & maintains air pressure required to operate air brakes & are either gear driven directly from the engine or belt driven. Most compressors use the truck’s lubrication & cooling systems, some are self-lubricated & some are air cooled. All compressors run continuously while the engine is running, but air compression is controlled and limited by a governor which loads or unloads the compressor. In the loaded stage, air is pumped into reservoirs. In the unloaded stage (with two cylinder compressors), the compressor pumps air back and forth between the two cylinders without supplying the reservoirs.

When air is compressed, the compressor takes in water vapor with the air, compresses the water vapor & puts it into the system as liquid water. Any water that accumulates in the vehicles air lines damages seals, valves & removes lubricants. In cold weather it can freeze blocking air lines & damaging air system components. The Air Dryer protects the vehicles air systems & components from this by drying the air passing through the air tanks and into the system via the desiccant cartridge. A coalescing cartridge has additional material to trap oil & aerosol particles. Water is then removed from the desiccant via a backflow of dried expanded air.
