95 civic sedan.....i bought a one man bleeding kit.. open valve 1/4 turn, plug hose on valve then to tube, pump brakes fill reservoir.. passenger rear and driver front bleed fine and all new fluid is running through it now.. passenger front and driver rear will not bleed ever with the valve open no fluid/air comes out...

i should be picking up the dual proportioning valve from the stealership today... hope fully this will fix it.. if not them im thinking it might be the line that runs from the Mc to the proportioning valve..
