    Soft Brakes Only When Engine Is On

    So I need help with my '97 C1500 with the infamous 10" rear brake drums. I have good, firm, high brake pressure when my engine is off, but they are completely gone and drop to the floor the moment the engine is on.

    NBS rear disc brakes on OBS 10 bolt

    Does anyone make adapters to put the NBS style calipers on the OBS 10 bolt 6 lug with the 10" drums? I've seen plenty of disc conversations but can't find much on the NBS brake swap. Is it easier to just swap a whole axle?
