Q: Brake pressure

Hi, car in Context is Skoda Octavia Mk1 2006 1.9 TDI it all started after a clutch replacement which included Flywheel, bearing & pressure plates, all set vehicle is back home, next day morning took the vehicle out and notice there is no pressure on the brake pedal, pedal goes all the way till the floor, took it to the mechanic back he said it could be a case of air locked up since clutch cables are connected with the same brake oil, we topped up bled brakes and there are the brakes, next day again no pressure, we would have cycled the same procedure for almost 4 days with no luck, checked for leakages, master cylinder, wheel cylinders, etc look good. finally took to the Skoda dealer for ABS bleed procedure which the SA claimed it was done and recommended Brake booster and cylinder replacement. after all this, this is what i found, one ABS line do not have oil coming in, all other lines are okay and no ABS warning light, also we found that oil is not supplied to RHR wheel, ABS motor works

My car has 82000 miles.
