Brakes - To stop or not to stop.....
Just replaced rear brake shoes and did springs etc. while I was at it. Adjusted everything and all seems fine. Except ......
Went for a drive around the block and pedal was soft ..... essentially non-existent. For some reason I decided to have a look under the front of the
car and there was brake fluid dripping off the body around the master cylinder. I gave it a wipe down to try and figure out what was going on and it
appeared that the hose from the reservoir had come loose on the 'nipple'. Tightened it all up gave the pedal pump and I can get pressure again.
Do I just need to bleed the system or is there more to it after breaking the circuit on the inlet side?

It would be a good idea to bleed the system again, as you said the pedal went soft indicating that there was air in the master cylinder, i always
bleed my brakes twice as a matter of course about a week after the initial bleed when i have driven the car a couple of hundred KLm's, i alway seem
to get a bit more air out of the system the second time.

If your flexible lines are old you might also want to look at changing them as well.

Also re adjust your rear shoes after about 100k's of driving.

I hd a weird airlock in my dual circuit system. Ended up having to clamp each of the fronts in turn to get the pedal hard and then bleed normally.
Been fine ever since but boy did it take some to figure out. Even my vac bleeder didn't remove all the air.

You could have a bit of air in the master cylinder...
only takes a small bubble to cause problems..
are the rear cylinders and rear hoses still original?
I would recommend replacing them all.
and keep bleeding slowly until the bubbles disappear..
cheers

New hose all round 12 months ago. Pedal is still mushy but the brake fluid is running clear in the hose. I'm guessing there is air in there somewhere
and the master cylinder seems the most logical.

you might not get a rock hard pedal with the dual circut master cylinder, none of my cars have that, you could try power bleeding them.
