Hi, I just bought my Porsche 944S and the only thing that isn't the best about it are the brakes. The strength is really bad, now I was wondering if anyone has any idea what the problem might be. I have adjasted the pressure of the oil on all the cylinders, the breaks pads are good, disks are also good. In my mind, the possible problem might be the master cylinder which might be pushing the oil back into the bottle, because on the boster has color damage since the oil leak. I can;t think of anything else, so is it the boster or the master cylinder, or perhaps something else. Thank you in advance,

 

When was the last time the brake fluid was completely flushed and re-bled?
