Thanks for taking the time to write that. I appreciate it. I am going towards the mechanical side of this because I have an obvious mismatch of parts or axles in too far. I have mechanical interference. Once that’s resolved... I am going to do another hard pressure bleed. If that fails... that master is coming off. I replaced a brand new GM master on a buddies Silverado last year. It was leaking internally and out the back. Back to the dealership and #2 worked. I put a Disc conversion on my wife’s 1960 F100 last winter. Bought the best quality 1960 Ford master I could find. Dead on arrival. Similar to this. We couldn’t get it fully bled ever. Put an Oreilly special on it and it was perfect. Bled in 2 minutes. We took that first master apart and the seals were gummy. It was the most sorry China rubber I’ve ever felt. It was smearing on the bore. I really don’t think it’s the master but my master cylinder DOA out of the box is pretty high lately.
