Leaking Matco PVPV-D parking break

Hi Guys
Just filled my brake system with brake fluid, and everything seems to be working well.
However the Matco PVPV-D parking break system is leaking from the Lever.
Has anyone encounter such issue? Defect internal O-ring?

Thanks!

No but I just installed one on the airplane I am building and printed the IPB from their website. Looks like you need new O-rings. Buna N, p/n 2-010, 3 of them. Give them a call and order the kit, they are really helpful.
 
Yep. Had a brand new one leak right from the start. The new split units gave me fits as there are two additional potential leak points. I found an old single block style and replaced it with that. I also had a leak from one of my master cylinders from Matco. Opened it up to find a big chunk of machined metal chip inside it. Not really impressed with their quality, but the price is right.
 
Mine has been safely stored since 1999 and just recently installed and charged with fluid. I guess their QC was better back then..;)
