Hi guys just recently replaced my na master cylinder,booster and front calipers which have been rebuilt and rotors to the turbo items. Now my problem is after ten or so minutes of driving the brakes are starting to drag. . The turbo booster has been vacum checked and its all good,so im guessing my master cylinder is buggerd. . Has anyone had this problem or know the fix. .Also have disc break rear end. Thanks

Is it all calipers doing it or only one?

Swapped over master cylinder with another 1" on the weekend. .And has fixed the problem. .Thanks

Probably the clearance wasn't right or gasket was missing between the booster ,and master cylinder which wasn't allowing them to release .
