Default e39 528i help

So I am in the throws of fixing up a 2000 528i 5speed I picked up for 500$. Body and interior were mint so I thought why not? Thus far I have replaced the clutch and rebuilt the vanos and suspension. So when I got the car the brakes were hard as a rock and I discovered the booster didnt hold a lick of vacuum. With that I put in a used working unit. Now comes the issue. When I bench bled the master I got good flow from the rear circuit but not the front two but didnt put too much stock into it. I have a spare master that is just as old that acted the same. I put it all back together and cant for the life of me get the front to spew any fluid at all when trying to bleed. Im thinking I have two worn out masters but wanted to see if you guys had any advice.

Thanks!

No fluid when bench bleeding or when in the car? I havent seen one that didnt squirt fluid in the vise. If on the car its possible you have a bench or collapse line. Disco the line from the caliper to check for fluid there, similar upstream if there is a union.

btw, pretty sure a new master is $50, 10% of the car!

Actually on the bench. Got very little flow compared to others I’ve done in the past.

At this point I’ve narrowed it down to a clogged valve in the unserviceable abs pump.

Not sure any help but my 99. 328is has full break system intact. If parts are the Same you can pull off what you need.

Thank you! Ill have the used unit by week's end. If you get a sec, take look at the part number on the top of the pump and see if it reads 265.225.005
