TR4A brake bleed nipples

[Tony Rhodes <ARhodes@compuserve.com>]

I have recently heard here about the "Speed Bleeder" (no it is not
a severe form of hemophilia) nipples.  They come in all kinds
of sizes and lengths.  What sizes do I need to my TR4A?  (Thread
size and length) I hope to get the correct ones without having to 
unscrew the current ones and therefore bleed my system WITHOUT 
the new nipples.

I do remember the front ones have a long neck.  Is that right?
