Ruairidh, following your comments regarding undoing the handbrake adjustment....
I have again this morning dismantled the brake system on Ruby, uncoupled all cables, released the brake rod and released the handbrake adjuster as suggested.
However by releasing the handbrake adjuster, I gained no additional movement of cross tube.
I have annotated the attached picture taken this morning, apologies if this is all stating the obvious but..
The handbrake bracket/ratchet is attached and permanently rivetted at two locations (A) to the chassis and is therefore non adjustable.
The handbrake lever © pivots around the single bolt located between the two rivets.
With the handbrake in its fully off location, it rests hard against the fixed bracket/ratchet at (B)
And therefore at point (D) no further clockwise rotation can be made to the cross tube, this to me sets, the locations of the two outer levers the rear brakes and the central lever to the front brakes.
And so the central brake levers starting position is as the attachment and the outer levers are just towards the rear of the car beyond top dead centre on the cross tube.
So as the car is up on axle stands, I checked each wheel and when rotating them all by hand, there is audible rubbing noise and slight resistance on each wheel and so there is slight contact between each drum and brake shoe.
I have then replaced the front cable and adjusted the compensator, then I tightened the foot brake rod adjuster to allow about an inch of movement on the foot brake pedal and when full pressure is applied there is still plenty of room above the floor.
I have then adjusted the rear cables and finally the handbrake adjuster to allow five notches on the ratchet before it locks the wheels.
I then rechecked all wheels to see if any had got any tighter.
With the handbrake fully applied I cannot move any of the wheels, I'm no Charles Atlas (giving my age away) but they appear pretty solid.
I have not taken her off the axle stands yet and road tested her, just in case there are any adverse comments on the process I have used or any additional work I need to do.
Apologies to all for keeping this thread going but I feel a little lost on the brakes.
Best regards
