Hurst Line Lock problems.

[Rory McNeil]

Wondering if anybody else has experienced any problems with their Hurst Line Lock solenoids . Last year, I installed a brand new Hurst Line Lock in my street strip car, and although it would hold pressure fine, after about 5 or so seconds, it was acting as if it had an internal leak, or was losing holding power. If you were on a hill, or the starting line, it would hold the car still, but then you could feel it slowly releasing on it`s own. There was no signs of brake fluid leaks, it just would not maintain pressure. So I bought another Hurst Line Lok, and installed it over the winter, and for the past couple of months, it has been working perfectly. But a few days ago, I noticed a small puddle on the garage floor, about a foot behind the drivers front tire. The brake pedal still felt fine, but the chamber for the front brakes was a bit low. The bottom of the Line Lock solenoid was damp, so I wiped it all up, and went over all the brake line fittings for the solenoid, which were all still tight. So I wiped it dry again, and had my wife step on the brake pedal, while I watched with a light and a mirror. Not leaking from any fittings, but appears to be leaking from the solenoid body itself, between the center chrome body, and the bottom seam. This is the Hurst Line Lock that has a finned body, and is chrome and polished aluminum. In my race car, I have a much older Hurst Line Lock, which looks totally different, and has been working flawlessly for almost 35 years. Just curious if these newer Hurst units are trash, or if I have just been unlucky.
