Did you bench bleed the master cylinder? Yes- several times
Is the vehicle fitted with a booster? Yes brand new
Did you check the rod depth in master cylinder ? No, but the MC came fitted to the booster, so I’m assuming it’s good
How much fluid comes out of the bleed nipples when you bleed them? A lot. It’s pretty consistent
What is the inside of the drum soaked with? It’s hard to tell. Some of it looks like grease, but I’m wondering if it’s just grime thatnwas picked up by leaking brake fluid. Weird thing is that the cylinder looks dry, however the little plate under it is soaked. Which could only be brake fluid.
Clamp off the flex hose feeding the rear brakes and try bleeding again....
Might be bad wheel cylinders...or bad axle seals or both....
Can you pump up a pedal at all? Nothing. It goes to the floor.
I’m going to do cylinder, pads and hardware. Everything is wet in there so I really should do it anyway. Keeping my fingers crossed that it works. It’s getting cold in CT and I want one more long ride before it snows!!
