Not all Safari coaches have an air compressor on the engine, but all coaches have a form of air braking for the park brake as far as I know. The coaches that do not have a compressor on the engine have an electrical compressor for the same functions, albeit with less air volume. This coach had an air compressor on the engine supplying a tank system. The air system was used for the horns, air activated step emergency park brake, the engine PAC brake as well there was coupler to supply air to fill tire. The way it was connected it could not be used to fill an air mattress and it would inject water in the the device being filled.

There was an air gauge on the dash and water drains for the air tank in the engine bay. The problem was, incompetent people at RV dealerships or repair centers had worked on the system and miss connected several key lines resulting in damage to equipment and incorrect operation. Water eventually was forced into the dash air-gauge destroying it, the air horns squeaked and the passenger slide would barely move in and out. This section address’s correcting these problems. It was relatively simple once a correct understanding of the system was gained. This Safari Coach does not have air system brakes to date I have not found one that has air brakes.
