Kerry, I would ever bow to Arwyn`s mechanical knowledge and experience compared to my own somewhat limited knowledge. And when it comes to brakes it is ever safest to employ expertise.
I am a child of the make do and mend generation thus my personal approach differs slightly.
I tend to think along the lines of...If the brakes have been worked on, and the cylinders forced back to replace shoes/pads, then it is possible that the m/cylinder has overflowed to some degree causing brake fluid to appear the be leaking from the reservoir by leaving traces on the casting..?
From a very dull memory I think those reservoirs can be separated from the casting once their fixing point(s) have been established and removed, either screws or perhaps a roll pin in the case of the cylinder in the image..?
With the fixing system removed the reservoir can be pulled free from the m/cylinder, at which point I might expect to find a sealing ring around each of the reservoir connections of which there will be two, one section of the reservoir for each of the two brake systems.
If you get to that stage I would hope that you found the cause of the leak, either a problem with the reservoir it`s self or the system of sealing..?
As it seems the issue is suspected to be on brake fluid storage and not from the pressurised side of brake operation, then with any reasonable mechanical aptitude available I might consider it worth investigating even if just to determine the cause. Ultimately you can parcel it up and send it to a repairer..
Rob, easy to replace seals...? I seem to remember some years back on eMog there was an issue with someone trying to remove the piston from a +8 dual circuit m/cylinder in order to replace the seal in the section loosing pressure, it was not straight forward. Memory fails me but I think it was perhaps the webmaster at Morganville who had the issue. The link does not provide info on brakes more a link to the webmasters Morgan history.
https://morganville.org/saga.htmlAs ever I expect Lorne at GoMoG will have covered all sorts of Morgan brake issues in detail, so worth rooting around on the site a bit...?
