18 Pdr Limber ( Aust )

[Graeme Stephens]

The Brake Cable actuates/pulls from the Truck (not yet), the cable runs to a wonderful Aussie cantilever, which at the top pulls a rod which is connected to a lever on a cross shaft that then rotates to both Brake back plates actioning thru cams to the Brake shoes.
If there is another connected unit, the through running cable at the bottom of the Cantilever then engages the second unit, to cause the same Braking - when there are no further towing units the Through running cable is parked on a hook at the rear of the mudguard.
A grease nipple is provided on the flex to help overcome friction.

it was even harder to understand when it was found as wreckage
