[W126 Coupe] Brakes and air

[Ronny 560sec]

My mechanic replaced today also the master cylinder of my 1987 SEC and used 
this time the newly bought Motiv pressure bleeder.
The brakes became firm. They did a test drive and first it start holding. 
Then they asked me to test drive the car. And when I started I felt directly 
the soft pedal that went all the way down slowly. Even pumping did not help.
Since this is happening again I think the master cylinder was OK. And they 
have used about 2 gallon of break fluid.
Any idea and advice
