Multiple problems with bleeding brakes

I returned the prop valve to Summit and bought another one from Inline Tube.

The leak at the port to the real line is gone but the thing leaks badly from the top at the crush washer. What gives??? Getting tired of this.

I had the same problem. I stole the prop valve from my Scamp, rebuilt it using the guts from one of the new, leaky valves, and put it in my wagon. That cured the leak.

I e-mailed Inline Tube about it and they said they never had a problem like I experienced. I asked them what fitting they used in the top port if they never had any leaks, but they didn't respond to that question.

Find an old prop valve, that will fix your leak.
