Brakes Deletion – How long?

Hello Have changed the 2 rear brake cheeks and loins at the T4 today.. It was quite good – to the very end.. Be sure to have kicked the brake pedal for 2 minutes – But neither air came out nor got sucked in.. (Put a tubing from the valve into a glass full of brake fluid and then pumped with the brake pedal) Did I do something wrong? I can now fully thresh the brake pedal – the car brakes NULL… (except in the front something) Did I just stop pumping too early while unloading? I also noticed that the screw that has a hole in the hose for the brake fluidity to the piston… Maybe that’s because of that?
