I have to say that the only problem I’ve ever had was when I asked a courier to wait whilst I opened and checked a delivery of two tyres before signing for them. He wasn’t happy but did wait. I believe that most of these drivers are “self employed” and paid by the delivery and only then if the item is left somewhere. Not sure about when they leave a card. We are retired now and usually at home so most of the regular couriers know this and we have become the unofficial default delivery address for many of our neighbours.

DHL delivered today, instead of their stated re-attempt tomorrow.
Perhaps it had something to do with my angry e-mail in their "contact DHL" box.
Result.
The cable arrived in a HUGE CARDBOARD BOX, no wonder it didn't fit through my letterbox.

Problem :
New right-rear cable fitted, freed up the seized pivoting bits inside the "drum",
fitted cheap temporary new grommets in the two steel braces over the axle, but intend to make much better nylon ones now that I know how to remove the 'left end' of this cable.
Fitted the end into the oblong joint thing with a pin and wire keep.

Brake test shows very little braking from that right side.
Left is still excellent.
Can I adjust in the oblong fitting?
Can I shorten the cable to the right by some mysterious method? Should I even contemplate that?

There should be some sort of auto-adjuster for the handbrake shoes if memory serves, maybe it's not work or needs a few operations of the handbark to settle it in.

That is interesting, but there's nothing inside the 'drums' on mine that is adjustable.
I'll go in early next week and fiddle about up on a ramp.

Presume cable is correct one so would not advise trying to shorten it.
Why not obtain correct grommets ?
As Paul said, fairly sure that there is some self adjusting device within the drum. I may be wrong, but I seem to recall a bridging device between the shoes, one end threaded into the opposite end with a ratchet device operated by a lever which moves as the handbrake is applied and lengthens the bridging device by screwing one end out which effectively adjusts the shoes out.

Just looked at my Haynes. Doesn’t mention that bridging device I refer to above so that must have been on a different car in the past. Sorry.
There is what Haynes refers to as “the operating mechanism” which must be replaced the right way up. There’s an arrow and the word “up” stamped into it.

I've also had a look at the HBoF and the operating mechanism doesn't seem to have any form of auto-adjuster so i must also have been thinking of a different car when i mentioned it above.

However, i've been thinking. Didn't you fit one of those "U" bracket compensator mounts on the back axle because the original was worn? I'd suggest moving it closer to the side that does work and then checking the cable adjustment (will probably need tightening) as that will effectively shorten the side with the shorter cable, tightening the adjustment on that side.

What you could do is lift the handbrake until the slack is just taken up on the left (i think the left cable is the long one that goes to the lever) then slacken the bracket and move it towards the left until both left and right cables feel like they have the same tension. You may want to lift the handbrake up or possibly down to improve the feel of the tension while you do this.

Once you get it to the point where they both feel equal in terms of tension, tighten the "U" bracket nuts, re-adjust the handbrake cable to give the correct amount of notches on the ratchet (clicks as you lift, 3-5 clicks after adjustment, 11 clicks max according to HBoF) and re-test.

Hopefully this should see you right on the first try but might need some "fettling".

It is very easy for me to make a special bracket with a pivot to replace the original wobbly A-frame-gizmo, though not as a first resort.

If yours still has the original thingy, I’ll call it a compensator, then the problem must be elsewhere and something needs fettling.
Was the handbrake more or less equal before the replacement cable?
Does the near side drum lock up whilst the offside is still free?
Don’t be offended, I’ve done it myself in the past, have you got everything back where it should be?
Whilst car is on hoist, is it possible to have someone operate the handbrake whilst you watch what is happening underneath?
Good luck.

None of the 700/900 series (including IRS) have these threaded adjusters on the opposite side of the shoes to the actuating mechanism. If some of you have seen them before then it'll be on 140/164 or 200 series. They were also reintroduced for the 850 but not sure what models after that have them. Why they were left out for the 700/900 is quite beyond me!!
