I have installed and bled the standard Van's dual brake system and it appears to be working ok however, when exercising the brakes I occasionally see an air bubble materialize in the semi transparent tubing between the fluid reservoir and the copilot brake cylinders. The standard brake installation has you use the nylon tee fitting at the reservoir rather than metal, I assume because it is low pressure at that point. I?m wondering if the vacuum or suction created in that line when pressing the brake pedals is sometimes strong enough to suck air through the nylon threaded fitting rather than fluid from the reservoir. I don?t have any fluid leaks but that doesn?t mean I couldn?t have a ?sucking air leak? . Has anyone else seen this phenomenon?
