Brake problem

Help I have a 1987 190D
I can drive my car for approx.30 minutes when the brakes get tighter and tighter. At this point you must relieve the pressure by bleeding one of the lines and then it is good to go again. I have replaced the master cylinder twice and had it power bled which lasted for two months. Does anyone have any suggestions?? qyouq

sounds like the brake booster has died and you're getting no vacuum assist.
