Toyota Yaris Drum Brake Bleed Nipples

[alexjblake]

Update;

I attempted to get the bleed nipples out last night and they weren’t shifting! Figured it was time for new brake cylinders as suggested earlier but after trying to get the brake line off it appears that bolt has suffered the same fate

What is the best way to move forwards from here?

Is cutting the brake pipe and reflaring it with a new brake pipe connector a possible way forwards? If yes would anyone happen to know the details of the brake cylinder thread?

I literally can’t see any other way of doing it
