[Rovernet] Brake failure switch

[Tom Rymes]

If they are, indeed, the same as an MGB, then you might consider getting 
one from John Twist at University Motors, or sending yours to him for 
rebuild.

He has a helpful video of what the switch is and how it works here:

I’ve read that they “mushroom” at the ends when tightened too much, causing them to not want to release. I’m now trying to figure out a good method to apply upward pressure while turning to get them out, so I can get to the rebuild.

In my parts book it only shows part #565550 as the whole 5 way junction-----I can't believe I would have to buy the whole assembly.  Even a used one which doesn't leak would be appreciated.
