    I have experianced a sudden loss of Braking power,this symptom came and went.Some times the pedle would be very sensative and other times the braking power would be very vauge.Now the braking feels like it has no boost at all.Much like when you have a crimped or leaking vacume hose.

    This is on a 1990 Suburban 6.2 Diesel.I have been told that the Hydro Boost assemply or more to the poiint one sensor is at fault.I would like to know where I can get one from.GM no longer lists the Boost assembly in its catalouges.

    Many thanks

    Try auto parts stores.

    Or wrecking yards.
