Spongy brake pedal
Okay so i just put on a rear disc conversion from teraflex and bled everything and my pedal was spongy. So then i went and purchased a zj proportioning valve with a disc brake setup. And it is still spongy. All my lines are brand new and there are noo leaks anywhere whhhaata could it be im really frustrated at this point

Was the master cylinder fluid maintained at above the "add" level when you were bleeding the brakes?
With the fluid level getting too low at the master cylinder may cause air to get into the master cylinder.
If you did, you might have to bench bled the master cylinder.
