Technical I need some help with brakes

[Uno driver]

Two years ago I bought Uno, everything works great except brakes. When I bought it, only right front brake worked like it should, at left side there was a problem with flexible hose (not returning fluid), rear brakes were not working at all (broken regulator). Rear brakes are still not working, left flexible hose was replaced.

I decided to keep this car for next two years as it's working great (I made 35.000km with no problems) but I really need to fix rear brakes. Now I have some free time, so I bought new regulator and started with work. I was spraying line fittings with spray for rusty bolts but I couldn't loosen them. After 2 hours I ended with one rounded fitting :bang:. I tried also with vice grips, no luck.

What should I do to loosen them? They are very rusty and bolted into aluminium.

Should I use welder and grinder to repair the head?

Is it possible that there is something else broken, not the regulator?

I solved my problem, brakes are working great .

Sorry that you received no replies

What did you have to do in the end? Grind off the fittings and replace the metal brake pipes?

I found out that regulator is working, I had problems because previous owner replaced the spring of the regulator with a different one

I replaced also front right flexible hose as it was in bad condition, I didn't have any problems with fitting there.

Thanks for that. I was thinking of replacing my regulator spring with a different one as well

I don't think I've ever had a rear brake regulator that worked on a Uno...

The rear brakes on my Turbo seem to be locking before the fronts, which can't be right!

I found ot that it's simple to check if it works. First you remove the spring, or lift a car, so spring is free. Then you need someone to press brake pedal, while you are looking at lever of the regulator. It should move a little (~1cm).

Is your car lowered? If it is, you should readyust the spring, as it's very sensible - some mm make a big difference

Yes, it is lowered - by about 40mm so well worth making an adjustment.
The spring wore a slot in the adjustment lever. I got hold of a better lever and keep meaning to get around to fitting it. Thanks for the advice!
