All reassembled and it appears to be free of leaks now 🤞
The Stahlbus valves are expensive but really nicely made and a doddle to bleed.
Probably overkill but they sure look pretty.

Also had trouble bleeding them so I've treated it to a new hard line and a pair of Stahlbus valves.
Threw in a new rubber grommet and bracket too; ##M539Restorations is either a good influence or, if you're my bank manager, a bad one 😁
That didn't go entirely to plan because someone had split the caliper previously with a chainsaw and then pried the seal out with a hammer.
I've lapped them and the recess for the O-ring was slightly raised as you can see from the bright ring around it.
