Hi Friends,
Just a quick question, when I pull the pin on the break safe switch on the drawbar should I hear the brake magnets make a humming/buzzing noise? I don't hear any noise what so ever coming from the brakes, the brake lights activate and that's it.
Appreciate any help

The onlu time you will hear humming/buzzing from the magnets is when they are being activated by a pulse controller up front.
The breakaway switch just connects the van battery to the brakes and is therefore fully ON, ie, no pulsing at all, so there will be no humming or buzzing possible.
The only thing you might hear is a, "snap/clack", ( no pop) as the magnets attach to the inside of the drum face.
Whenever you pull the pin to
check you can
check if the wheels are locked by jacking up each side and then trying to turn the wheel.
