Replaced the master cylinder in 1989 toyota cressida and rear pumps fluid fine but fronts are intermitent, tried vacume bleed and drew out fuid from caliper to the point it withdrew from rotor. Tried pressure bleed and get no fluid at caliper? ABS?
Sounds like you need to check the flex hoses, remove the line at just before flex hose, does fluid come out now? If yes replace the hoses, Next remove the bleeder from the caliper, does it flow good now? If yes replace bleeder(clogged with dirt).

Replaced the flex hoses and bleeders are free and clear

Really bench bleed master, or open bleeders on front and allow them to gravity bleed. Don't let master go empty!

I have replaced the flex lines and the bleeders are free and clear gone through the system section by section can not draw fluid even at the port for the front at the cylinder

Master is bench bled very well left fronts open over night still dry removed line at master cyl. And no fluid leaks out

If no fluid leaks out return the master for another one. Compensting port is blocked.
