I am flushing the 10-year old brake fluid from the system and bleeding the air out using a pistol-grip vacuum bleeder. As anyone who has attempted this knows, it is not easy to get all the air out. I believe the bleeder valves now on my coach are a straight-through design. It appears to me that there is a possibility of introducing air into the system when the valve is open, essentially through the threads. There is another bleeder valve design that has a spring loaded ball inside that could help prevent air being introduced while the valve is open. What do you guys think? If one design is better than another now would be the time to make the change. I'm building a pressure bleeder at the moment in the hope of finally doing a good job of getting the air out. Frankly, I'm not sure if I've ever had all the air out of the system in the 13-years I've owned the coach.
Appreciate thoughts on which bleeder valve design is best?
Thanks,
