No pressure after cleaning M/C and dividers
 

I pulled the master cylinder and dividers out my 928 and attempted to clean everything out (because brakes were locking Up) I put everything back together and now I can't get any pressure when bleeding the brakes. What did I do wrong?

Maybe the locking problem was related some some other massive failsure relate to the master and it's done.

Lets start with your procedure to bleed brakes. Did you bench bleed the mc? Did you take the mc apart? Seals replaced.

I bench bled the MC as best I could ( think I may have messed it up putting it back on) does it have to be perfectly bench bled or can you still get the air out from bleeding from bleeder screws? ,also I did not replace the seals because it is fairly new, about a month.

Master cylinder is brand new.

What are the signs of a bad brake booster? I did pull the line but I did not plug it so it was still sucking air.
