Brake thing identification

[marshall cook]

I ordered the AP Racing master cylinder from CC and it fixed all my soft pedal issues.

I had these things here on the old Girling master and thought they may be bias adjusters so left them on, all working well, just wondering, are they original?

I don't think they are bias adjusters as to work you would expect them to transfer fluid from one circuit to the other, not just restrict a circuit. The only time I have come across things like this was to block off a pipe for maintenance, it saves the system draining down if you need to remove a slave cyloinder or pipe.

Line locks?

That's exactly what I think they are Anthony. Most line locks can be operated after operating the footbrake, in this case it looks unlikely but line locking for maintenance is a possibility IMO.

Thanks folks! Seems like a lot of effort to keep from bleeding the lines a little less.
