hows your pedal feeling Perry?Could be a block in the lines-hopefully you have fluid through all the cylinders.when i did my brothers 63 c60 it took time for the pedal to come up and stay hard.After driving the truck for a bit all this went AWAY.I think its a finiky process with the hydrovac. Keep us posted please because im doing this same job this weekend to my 65 c60!Do not go nuts! Timbuk
