the lines arent cracked the calipers dont leak its just a pain in the a**




check you haven't killed the master cyl by pushing the pedal right to the floor.

after that keep bleeding, 600ml isn't enough.

i agree. damaged the primary and secondary piston seals. so when the bleeder is cracked and there is no pressure it feels alright. but when trying to brake the fluid will just flow straight passed the seals

i had a problem with my mont last week, lost brakes my first thought was booster but peddle was soft? after going over it i ended up back at the booster and fund that the iner seal in the booster was shot! Air was pumping back out the shaft at your feet.
Another booster later and she brakes even better then before, so never second doubt the booster with out a good going over..

To be honest mate, i think its time you called a tow truck or a mobile brake repairer/mechanic.
