I've a leak in a nice, recently rebuild master.
A couple of years ago I found a mob in Dublin VA, USA, called New River cycle Salvage. I probably got the info from here.
They do glass replacement sight glasses.
You pull out the old plastic sight glass, give everything a clean.
Their glass is just a simple disk.
You're best to do a few test fits first. Mine were very promising
I salvaged the o-ring, but it is not necessary. When I set the glass into the silicone o-ring the silicone spread out more than I expected.
I'll let it cure and fill it with fluid to see if it leaks.
I did a messy job this first time. If it leaks I'll pop it out and not use the o-ring. I used clear RTV silicone. Without the o-ring i'd use black.
New River have both glass and plastic. I'm using the glass. It feels pretty strong, and I'm quietly confident I can save it, give it a clean and re-use it, but I did buy spares just in case....
That is remarkably clear. I can barely see thru the plastic sights for the master and the engine oil.
I see from the bottle caps that replacement is a two beer job. :morning1:
Is there no concern about contaminating the brake fluid with silicone?
I did wonder about that Rick.
The instructions said to use clear RTV silicone, and the one i chose an automotive brand.

He he he, I have to down tools after 3. My confidence increases, but the workmanship decreases :drinks:
