Buddies 86 c20 was in a fire awhile back when his girlfriends ex-boyfriend set fire to his house. The truck was in a garage and the grill, hood and front fenders as well as the engine bay was brunt up a little. I'm wondering if the Booster and Master Cylinder would be save to use? its black, but not melted and the cap on the booster is still solid (its aluminum it looks like). Is there anything inside that can melt or cause problems? I'm wanting to pull the 3/4ton booster, MC, lines and distribution block in the front and plumb them on my frame before the body goes on. Also the back brake line from the resivor has a line tapped into it whats that for? Line lock?
