Also tap them with a light hammer first.   I generallly gingerly try to tighten seized fittings before removal.

And try a 6-sided socket first, NOT a spanner.

Calm down,  Mike!

 You only need to bleed the calipers from the top nipples. You shouldn’t need a pressure bleeder, (although you can use one if you want), but the usual process with the wife as a pedal operator should work just fine.

Works for me, anyway.

Sound like some Vauxhall calipers. Leave them bottom nipples well alone - nip them back up. You have to bleed from the top - air rises chap ?

Mine’s alright until we get in the car. Makes more noise than the car does.

Ignore the lower nipple - bleed from the top one only.

post up a picture of the caliper Mike

Start with the rear LH...then rear RH...then front LH and finally front RH. The underneath bloke is in control...take length of rubber hose and fit to nipple. Put end of hose in jamjar with fluid in, make sure it's submerged. Open nipple...call "Brakes ON!". Inside bod pushes pedal slowly to the floor, and holds it there, calls out "Brakes ON!" Underneath bloke closes nipple and calls "Brakes OFF!" and inside man releases the pedal. Bubbles will have appeared in the fluid in the jar as the pedal is depressed. Repeat process until no further bubbles. Check as you go to ensure that the fluid reservoir doesn't run dry...refill as necessary...if it does run dry, start over...and DON'T DO IT AGAIN(!) Then proceed in sequence for the remaining calipers...

As has been said, only use the top bleed nipples as air rises.

On my Airtourer aeroplane, the nipples were only at the bottom, and the only way to bleed it was to pump the fluid in from the bottom nipples and fill the system that way...sometimes it even worked(!)

Have fun......

If the system has been empty or the master cylinder replaced you might have to bench bleed the master cylinder first if its the tandem cylinder used on Turbo or S3. There are procedures for this on the web as many cars use this type.

I had to, last time I did this. No amount of doing the usual pedal pressing would work, no fluid at all would ever come out the front ones. I think the reason was the front piston in the master cylinder had got pushed in by the first down stroke and just stayed there, blocking off the fluid entry, and only the rear piston retracted.

I also found that using the Sealey pressure bleeder I normally use didnt work at all on these brakes, it actually made them worse.

I have had success with gravity bleeding. You can do it on your own. Quick google search will give you all the info.

That method might well have worked in my case and avoided a lot of hassle. With the master cylinder in its rest position without pumping at all, maybe simply waiting for it to fill and go through the system. May have taken a while but saved time overall.

I can even hear it with the window down.
