As long as you didn't loosen the thread at all before it sheered then it's perfectly safe to drive.

The bottom half of the nipple is still in place, and provided the thread is seized (probably won't be going anywhere if it sheered off), then the tapered seat will still be maintaining a seal against the mating surface.

Not worth drilling and tapping out. Easier to replace the lot.

It moved hardly at all, I did try both directions but not much moved. Handbrake  will also work won’t it so I have a back up 

Ah the wheel cylinder is only £20 on euro car parts, so not as bad a problem as I thought? I’m getting the mechanic to do it though.

You'll have to strip the brakes down as the cylinder is inside pressing against the shoes, and then bleed them again. Sometimes the drum can rust weld itself on so might require a bit of persuasion to remove. You'll be paying way more in labour than the actual part.

This is a good example of ‘ if it ain’t broke……….’    Working on cars for over 40 years and having had some snapped bleed screws and stripped bleed screws threads, I will never trying undoing a bleed screw unless absolutely necessary, or it just ends up being one of those jobs that goes wrong and you wish you never started. I know the theory of why fluid should be changed periodically

I´m also thinking of doing this on my 1.6 Petrol Mk2 2009.

 

There´s nothing wrong with it. But I do think it needs a change of the fluid, I would doubt this has been done in many years with it.

I´m keen to do it myself. Love tinkering with it myself and always enjoy the peace of mind knowing it has actually been done. I also enjoy learning with this kind of thingn. Previous chap in this thread had some bad luck though. 

 

What are you´re thoughts? Take a stab at it myself, leave it alone, or take it to mechanic to change the fluid ?

You and me both!

I assume that as no air is introduced into the system you would be all good? If your helper pumped and kept pressure on the brake pedal before you cracked the bleed valve nut, then once the pedal had hit the floor tell the helper to keep it there until you’ve retightened the nut. Surely this would ensure no air is sucked back up into the braking system? 

Obviously checking between bleeds at the braking fluid reservoir has not dropped below minimum and topping up as necessary. 

Using some kind of penetrating spray to help loosen the brake bleed valve nut is an essential to prevent the nut from shearing and causing yourself all kinds of problems.

Good advice, only a year too late to help @dizzydone
