Brake pedal acationaly looses pressure have to pump brakes have a vaccum issue ongoing with multiple vacume port on top of intake manifold rear of engine driver side this has caused I doling problems, Etc. Hoses blow off sometimes even when starting engine will back fire and cause hose to come off. Hoses seem to be in good shape, maybe alittle loose? Will be driving, and brakes are not really there. This truck has been very well taken care of by mother, always took car in when something was up. Could this be a vacume problem? The power brake unit looks brand new! This ford ranger xlt has 4.0 motor
