You're right, the shoes are designed to float as they only have stops at the rear ends of the shoes. This float enable the shoes to act as a pair together and lock on more evenly and lock on harder as the wheel pushes them round against the stop.

All 700/900's with live axle have this set-up which is disappointingly crude and under-engineered unlike most of the rest of the car.

When the shoes are new, the operating lever that's attached to the end of the cable is in an approximately vertical position. As the linings wear, when the shoes engage with the drum, they and the expander mechanism do so further apart and the lever is pulled in further toward the centre of the vehicle to enable this. Over a period of time, the lever goes from being vertical to being at an angle and there comes a point when the lever fouls the outboard entrance of the hole in the hub carrier through which the cable passes. When the shoes are in contact with the drum, both the shoes and the expander mechanism/lever are dragged round together until they contact the stops on the hub carrier. When the wheels roll FORWARDS, the lever is moved upwards, jammed against the hole entrance and is prevented from moving any further inward so the expander cannot apply any more force to the shoes. When the wheels roll BACKWARDS, the lever is moved downwards, freed away from the hole entrance and allowed to move further inward and the expander is allowed apply more braking force. |

Handbrake is OK now with the new discs, but already ordered new shoes too. Job's a good 'un.
