Brake bleeding for the BMW 530d E61.

[Lovelyas]

Greetings, everyone.
I hope everything is satisfactory.

I am experiencing a headache accompanied with haemorrhaging.

While driving, the rear passenger brake line (UK) ruptured.
Secure the vehicle and spouse in a secure location inside an Aldi parking lot.
The reservoir was almost devoid of water, exhibiting just a little trickle.
I installed fresh DOT 4 fluid and a friend arrived with a vehicle trailer.
Transported the vehicle to my sister's residence, rather than to my parents' house where we typically service all our automobiles.
Repaired the pipe by cutting and joining it with copper.
& Attempted to bleed.

Reservoir full. The rear driver's bleed nipple is open, but no fluid has emerged after some time. Two men inflicted injury on me while I was on the pedal, and my father did so on my breast. Open foot on; close foot off. I attempted it perhaps five times without success. Inspected the back passenger area... same... no findings.
We then operated the engine and repeated the procedure with two individuals... No results.
My father has never failed to bleed brake fluid. He successfully replaced the ABS pump on a 2008 Opel Astra and bled the system effectively.
He said that my system is filled with air.
We attempted for around 2 to 3 hours; throughout that period, we performed the two-man procedure and sequentially opened each rear nipple for about 10 minutes.

Nothing.

Can you provide assistance with any ideas?

I just purchased a tool but am awaiting its arrival.
Similar to a pump bleeder.
I will show you a photograph.

Any suggestions, please.
Thank you.

If the system is totally emptied, a pressure bleeder must be used in conjunction with the ABS bleeding method in diagnostics.

[Lovelyas]

What is the function of the diagnostic?

Thank you

[Bleakerje]

It follows a systematic procedure for purging the ABS system and valves. Essentially instructs you to apply pressure to the bleeder and then sequentially loosen one bleed nipple at a time while the ABS operates.

[Lovelyas]

By use the bleed pump gadget I purchased above #3, I am essentially engaging in a futile effort.

Do you believe the instrument will exert sufficient pressure on the system to activate the abs?

Thank you, Bleakerje. As I said, my father performed one on an Opel Astra, which included an ABS replacement and a complete system re-bleed. I assume they are not all identical.

[Bleakerje]

While pressure leaking may suffice, my experience indicates that until the system undergoes diagnostics after being depleted, the brake pedal performance remains suboptimal.

you need to replace abs
