Replaced master cylinder as per instructions
Bench bled & line bled brakes
Pedal still sometimes fades after holding, almost like
ABS kicking in but no indication on dash.
Have rebleed system 3 times and still shows some air. System has crusie switch on cylinder & extra lower port for bleeding. Bled them 1st then wheels in correct order rr lr rf lf, np leakage detected anywere.
May be replacement cylinder bad?

You can bleed it. Bench bleed the master by getting brass plugs and screw them into the two ports, then pump the master until you cant move the piston any more. Attach the lines, Have an aide press and hold the pedal crack the lines and retighten, repeat this till all air is removed at the lines, Don't let the master run dry, bleed rear cylinders by opening the bleeders and wait until the fluid dripps out. Close bleeders. Make sure the rears are properly adjusted, then test the pedal hieght
