After rear disc conversion got no brake(help)

[civicVI]

i just did the rear disc conversion on my civic eg hb
now got no brake
just have E brake
i jump into the driver seat and press the brake pedal down and then release it up.need to did that few times then can feel the brake.
i was thinking have some air inside the master cylinder reservoir/system/line .so i pump the brakes several times and then loosen the nipple.
at last still same
just wondering whats wrong?

u need to bleed from the back 1st then do the fronts last

[ksl]

when you press the brake pedals, is it soft, or just like normal when to apply other brake?

but high chance there is still air in it.

its soft
i bleed them more then 2 hours still same
when start engine the brake will be soft
when off engine the brake will be a little bit hard

checked
no leak
just test drive .. the brake so soft need to press the brake pedal down(at the bottom)then it can stop.

is it wrong step??
i need to bleed from the back frist (a pair) then front(a pair)?
because i bleed them one side then the other side

i was wondering may be the brake master cylinder not big enough but i just up grade the rear so should be ok since i did some research from ozhonda

correct. not side to side, but both rears, then both fronts

make sure you bleed them properly
