Check the operation of system before releasing vehicle! (Charge air tank with shop air, pull pin from switch, vehicle’s brakes should be applied and released after pin pushes back in.)  TEST every 30 days.


1.  The small air tank (A) may be located anywhere on the towed vehicle in any position.

2.  The diverter valve (B) is to be located in a convenient place on the towed vehicle in as much an upright position as possible. On this valve are two electrical wires. One is to be grounded, the other to the trip switch. The remaining wire on the trip switch is connected to the + side of battery with a fuse holder (which is supplied).

3.  The trip switch (C) controls the operation of Breakaway System. This switch should be mounted on a solid surface and be able to swivel left or right.

4.  The pillow block (D) or anchor block should be mounted to a solid surface. This block anchors the air line in the event of a breakaway. This ensures the air line will break and not pull the valve from its mounting surface.

·        If the towed vehicle should become detached from the coach, the cable plug will be removed and close the switch. Should the system be activated accidentally, you can reinsert the plastic plug in the trip switch and the brakes will release (PLUG MUST BE PUSHED IN TILL IT SNAPS IN PLACE). Plug must remain in switch at all times. A key ring can be attached to plug in order to remove cable with a hook attached.

·      Before any trip, fully apply brakes on coach for approx. 1 min. to ensure full air pressure in small tank. When vehicle is not to be towed for a long period of time, the fuse should be removed to prevent accidental deployment of the system.  NOTE: TEST the Plug every 30 days to make sure the contacts are in good working order.

·      If pin for switch is lost, brakes can be released by pulling fuse and disabling breakaway.

·        Be sure that the steel cable is long enough to prevent any accidental deployment of the Breakaway System. The cable should be at least one foot longer than necessary, when the car is hooked up in a towing position. Sharp turns must be taken into consideration. Take great care in routing of cable as not to bind on anything. M&G Engineering is not responsible for accidental deployment of Breakaway System due to short cable, road debris hitting cable, or improper routing of cable.

                                 One-year warranty on diverter valve and trip switch.
