Brake Issue/ Low Pedal

[GalDemSuga]

I will look into this in a few days. Weather conditions suck right now.

....check valve.

Follow your rear brakes all the way back up to the MC. If you don't find a check valve, I would start with that.

Basically fordums post boiled down to "your abs may or may not have had a built in check valve, its worth a shot to take a look."

Definitely easier/cheaper than the master cylinder.
