Whilst it has taken me about a year to actually finish this project i didn't want to start taking the car apart when i was due to move last year. Having moved in 7 months ago and now having a garage i have been able to over the winter do a few of the jobs that i was unable to do working on the drive.
The main one being a working handbrake which will stay working and not go out of adjustment just as quick.
Still got to get the uprights powder coated and finish off some of the mounts but having set it all up today it works great. Will probably need a bit of adjustment when i actually drive the car, but initial impressions are good.
I tried keeping it simple not over engineering anything and trying to keep the original cables. Which i have been able to do. All is needed is to cut the existing ends off and shorten the cable about 80mm. New mounts were welded to the uprights as were some cable guides.
I've added a spring on the cable to help return it to the off position with some rubber bellows to project from the elements.

Is there much scope to change to a brake disc without the integrated drum, which wouldn't cost the Earth?
I like your thinking! Discs wouldn't be a problem.
Custom bells would need to be made.
Shame the weight saving would be from the wrong end of the car, still its unsprung weight
Peter are you going to do some on the road testing? Maybe a MOT brake test readout see how it compares to standard?
Well done for a mod to make the cerb more reliable / usable
That would work even better if you could engineer it so the cable pulled at 90 degrees (or as close as) to the caliper lever (maybe by incorporating another pivoted lever?)
I thought you were working on a lever system to exert extra pull on the existing handbrake shoes at one point? I used to do a mod where I cut the little slave lever on the handbrake mechanism in the drum and lengthened it. The increase in length was small but every little helps. I later realised that one of the main reasons the handbrake doesn't work well is internal corrosion of the cables themselves. Replacing the cables usually makes a world of difference. Also making sure the cable is attached to the top hold on the handbrake itself. It's amazing how many cables are still running on the lower hole and so reducing effort over the cable at source.
Good work

Good work
I'll check my hole position today and find out. All my cables move smoothly.
My handbrake never work very well even with new shoes springs etc. And could never trust it.
Couple of MOT mentioned it and said as long as you know. But the last Mot was a jobs worth even tho I said to him at the time.

I remember doing a handbrake mod for a new customer once, tried the handbrake outside on the hill and it worked so well it promptly smashed the reaction lug off the alloy backplate. I had to buy a whole hub assembly off a breaker just to get the backplate. That was an awkward conversation with a new customer, having to explain how I'd broken his car!
