ok heres the setup. 99 calipers up front and drums in the back. 95 master cylinder and 3-2 conversion. when I first installed it everything was gravy. Car then had an engine fire and sat for a while. Everything is now in running condition again but my brake pedal truly feels like I have to stand on it and jump up and down to get it to stop. Fluid level is good and there is no air in the system. Could the heat from the fire have killed my brake booster? Its the only thing I can think of that would cause this issue.
