I have vans standard dual braking system installed as per plans. I read all the threads on bleeding the brakes and decided to do the pump up method. It worked except there were air bubbles around the cylinders. I then bled them conventionally just like a car, making sure to never run the reservoir dry. I thought that got it but apparently not. I saw bubbles in the lines today. I rigged up a reservoir that holds 1 litre of fluid and connected it to the firewall reservoir then I attached a one man bleeding bottle to each brake and pumped a ton of fluid through. I can't get rid of the bubbles at the cylinders. It's almost as if air is leaking into the lines there. There are no fluid leaks anywhere so I think the integrity of the lines is good. Anybody else run into this?
