hi . i have a vivaro , 2008 . my problem is my brakes are all coming on when driving. it is all brakes front and back. if i unplug the vacuum pipe from the servo the brakes are again fine. it is worse when the engine is hot. i have replaced the abs unit, the master cylinder and the servo and the problem is still here. allpads, discs , calipers are fine. could this be a management problem ?
