I've only seen 2 Vanagon BPV's. ('81 and '85) Neither had an adjustment. Oddly, P. 47.8 Bentley says "push lever on brake pressure...." when bleeding. I recall a thread in archives about that. AFAIK, no one here has mentioned having a lever on their BPV. Likely a typo in Bentley. Yah I should have posted my 2 questions in one post except one relates to poss. trapped air, and the other is about rate of flow. Thanks,
