There are plenty of accounts online of the repop metering valves leaking. My first one from Inline Tubes leaked so they sent me another one. The second leaked ever so slightly so I stuck with it. Now as I actually drive and brake, the thing leaks REAL bad under pressure from the pedal. I removed it and took it apart to find a very poorly made seal. From my readings online this seal cannot be bought separately.

Am I faced with continuing to get replacements until I receive one that doesn't leak? Has this bad part/leaking been resolved in the last couple of years and I missed it?

I understand that this valve delays the front discs for a split second when the pedal is applied. Can this thing be "gutted" and plugged, removing the "delay" and not adversely affect the braking?
