Bleeding brakes/uneven clamping force

Hi!

 

i have one last little problem with the supra since the rebuild. the brakes brakes dangerously uneven, the car has been in my garage the whole winter and is parked in the garage every night. this is what i have done and with no sucess.

 

Fírst off i bled the brakes the usual way starting with Left rear,right rear,left front and right front. as i havent got the problem solved i have bled them with around 1.5liters passing trough the system.

I Bled the Master cylinder and here is a question, i get more fluid from rear port (closest to stearing wheel) or more like it comes from that port first and seems to come more form that one aswell.

 

since i painted my engine bay and i also painted the brake booster, i removed the master cylinder (fitted new gasket) and i also removed the ABS unit. as far as i know the ABS unit should be bled using the nipple on the calipers.

 

the pedal feel is hard and i dont get any airbubbles from the bleed nippels.

 

So any ideas?

 

should the master cylinder flow exactly the same amount at the same time? as there is a bit of a delay to get any fluid from the front port.

 

i have tried bleeding them like 4 times now and i got the feeling its not air in the system, might be in mastercylinder but i truely dubt it as ive bleed the Master 3 times now.

 

i aslo doubt that the calipers are sized as its been in my garage the whole time and i did not have this problem when i put it there.

 

Gratefull for any help or ideas. (yes i did use the search function but i did not have any luck finding info)
