Thank you Rossocorsa. I now have a working handbrake :-)
Weekend of work: Nigel came over for a coffee and helped me with a few pointers
After he had gone I finished my tank re-instillation, connected all the hoses up and got the engine running again. Then I did the front bushes, they were hand made from brittle nylon type substance and a couple had broken. ARB on the front actually had newish looking poly-bushes. Tbh this is the only set of bushes you can get from the normal suppliers I think. I have the rear ones baring one set that are only available in orange at the moment. Rear bushes are shot almost non-existent.
Today I replaced the handbrake cable, HT leads and started working on the new washer bottle. One thing which was odd, I noticed a rear piston boot off, so I whipped the caliper off, and when I removed the piston boot off I found a piston seal inside, no leaks though. I will rebuild this caliper I think. It must have a seal inside surely? Put the boot back on and tested again. Brakes feel really firm tbh.
I cleaned all the calipers and put some pluzgas on the hose connections and nipple thread bases. I think its all been apart recently it seems, and the nipples are brass and look new. I have flexy hoses and compensator coming.
This week maybe I will do a compression test, and change the timing belt and pump.
Nigel suggested I get the rad checked out. I will price this out and order a new rotor arm and a battery as it seems pretty dead. I keep conditioning it but I will not hold on to a charge. I guess it could be something else but this is worth a try first.
All the lights are working. I didnt test the brake lights though as I was on my own. New washer motor works from the switchgear, I was concerned at this stalk is repaired.
So I need battery, caliper rebuild kit, look at the missing rear bushes so maybe they will have to be orange? I need a bunch of nuts and bolt also.
