Hi, I have a strange brake behavior, it started with front right brake caliper got stock when driving and that side got over heated when using the car and the brakepedal sunk towards the floor when you keept it under presure. I changed the front discs and pads. Nothing changed.

And the i changed the right caliper, suspected that it could have a internal leak from overheating. And the problem was still there. 

Then i changed the master brakecylinder for the same sus****ion, that it could have a leak on the inside. But the problem is still there. Im running out of options. I turned it over for the mechanics and they have bleed the system twice, floded the system to make sure it doesnt have any air in the system. But nothing works.... no error messages, accept from turbo charger booster. 

Hi

 

Surely the only remaining option is the abs module? Can't think of anything else that would cause your symptoms. 

Yeah im leaning towards that aswell. Or rather im running out of parts to swap. But I would think that I would get some sort of error massage if that would be the case. But maybe not.
