Bleeding servo/disc set up.

[paulio0898]

Hi All,

Just converted to midget discs and new servo. tiny Seal removed from front of master cylinder.

Im not sure about the master cylinder. I see lots of fluid returning to the reservoir after the brakes are released, does that mean the seals are damaged inside?
I tried master cylinder outlet blanked off with a bleed nipple, its rock solid.
But when I connect things back to brake circuit, I cant seem to bleed brakes and occasionally pedal just pushes to floor?
Is that a symptom of bad master cylinder ?

Any help gratefully received

Thanks
Paul
