Brake proportioning valve

Well im not the only one with crazy messed up brakes been working on mine for a while found out master is leaking fluid in to the booster so new master new booster weds as far as bleeding the rears are a steady drip gravity bleed front flow good so I'm thinking the sensor on the proportion valve is throwing the ABS and brake light on cause the presser drop from the master into the booster

if the proportioning valve has closed off the rear brake circuits, that will indeed annoy the ABS system.
Verify your rear brake circuit is intact..... then have a friend pump up the brakes, and HOLD pressure, while you crack open one of the FRONT bleeders. That should reset the prop valve, and get your rears working again.
