Re: Leaky Valve
I had a brand new Combination Valve leak on my 71 Malibu before I even got to bleed the brakes. My valve is mounted on the drivers side frame rail. I did a write up on it with a poll but I can't find it. The valves that were failing the most were coming from Inline Tube where I bought my first one from. I bought my second one from the Right Stuff and haven't had any problems with it. There were quite a few failing back around 2015 but I haven't heard of any lately.
