Hi All,

I have put this on my Pug 4x4 thread but hoped this might find a wider audience here. The rear part of the 4x4 master cylinder has a gold coloured star drive plug with a rubber seal (I think) and under it in the hole is a 1.5 ish inch length of metal with a bulb on each end and steel pin sides (the pics explain it better). My question is...what does this do? I want to use the master but not in abs. I cannot get the gold plug in with the 1.5 inch metal bit in the way....any help appreciated.



1.5 inch metal thing is on the far left, the gold plug to the right of it...the second pic shows the hole it goes in to.





Above is the hole.
