Rock Auto will set up an RMA with A1 Cardone in TX and will provide you a shipping label to send your hydrovac in for a rebuild. Takes a few days. The hydrovac makes a HUGE difference in braking. I don't mean to sound like a nanny, but I can't imagine the conversation with the insurance company if you get in a wreck and disabled your factory brake booster and that's why I had mine rebuilt.
