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

Mine returns fluid to master the same, just replaced my servo, bleed using servo out pipe first then wheels, jacking up the end you are bleeding to get wheel cylinder highe than master helps.
