leaking brake valve
Have you been buying, and using one of those China repop, proportioning valves that lots of internet sellers, vendors, are selling?
If so, those are notorious for being defective, and or leakers, right from the start.
Lots and lots of people have problems with them.
Do a search on the problem.
GOOGLE, or the web sites, like you are doing here.
I used to sell lots of excellent used valves, here on this forum, until i sold them all.
If you can find someone with a good used valve to sell to you, that would be the way to go, in my opinion.
But finding someone with a good valve, is getting harder and harder, to come across, now a days.
Good luck.
