Problem with brakes

I have an w140 280 and have problem with the bakes. I swaped the brakelines and 2 calipters and after that the pedal got soft. I am able to pump up presure but when i hold it, it slowly goes to the floor. I have tried swaping out the main cylinder and it didnt help. Any suggestions?

I had the same symptoms with a bad ABS/ASR module. replaced with a working unit from CA. Pedal and brakes are now restored. This presented itself after brake work as well. 92 500SEL.
