Welcome,John 53!Your brake pedal is connected directly to your M.C. It's your M.C. that froze-up,not the hydrovac. more than likely,though,it sounds like your hydrovac is bleeding fluid from your M.C.,(as long as you don't see any "wet" tires,or leaks/puddles. My M.C. is sucked dry,if sitting for 3-6 months. from other posts,I gathered that the seals in the hydrovac caused the leak. After filling the reservoir,and pumping the brakes,they work great,until I let the truck sit for extended periods. But now it's time to re-build/repair/replace all of the components. I REALLY want to drive '"Tater" to K.C.,this September,and make it there and home again,in one (un-damaged) piece.
