I got a new TRW branded master cylinder. Successfully replaced the master cylinder:
After the MC removed, corrosion on the booster is visible.
Removed the rust with a Dremel, the yellow plastic cap from the defective MC was used as cover.
Primed ...
... and painted.
After installation of the new MC I did the "bench" bleeding process with the help of some plastic and rubber hose pieces. You can pump the paddle while sitting in the seat and see the clear hoses through the gap between the open hood and the windshield cowl. Keep the clear plastic lines as short as possible and submerge the other ends into the brake fluid of the completely filled reservoir. Otherwise you will not get the bubbles out and suck them in again. It took quite a while to get all the bubbles out.
After a traditional bleeding with the help of my son I did the "HDC bleeding" and then a power bleeding with the self made kit above. Take the ABS relay out, bridge the ABS relay contacts, open bleeder screw, let it flow until clean and no bubbles, close bleeder screw (ignition always off).
I probably need to step back to the beginning on bleeding mine.
