I am having a problem with a leaking "welch" plug on an installed master cylinder that I purchased in a group buy from a vendor here. We all know what a pain it is to change a master cylinder so I am hoping to avoid that process. I see that bbrock had the same issue and was able to fix outside of the car. Has anyone fixed the welch plug in the car with any success? I really don't want to take it out.
Thanks for any good ideas. |

@rudedude it does take a fair amount of pressure but I think a hefty c-clamp could provide it.
@iankarr I don't remember for sure what size I used but it was probably 12mm which is what Eric Shea recommends for the welch plugs on the rear calipers. I remember thinking the MC welch plug was about the same size so probably stuck with 12mm. I think the idea is to use a size that presses the domed center to flatten out the plug so it expands the diameter. |
