I recently did a front to rear brake rebuild on a 1971 El Camino 454 SS, including all front brake lines. I've been over and over the system and multiple bleeds but I still get a hard pedal and can not lock the brakes up. It feels like no boost from the (new) booster but it passes the pedal tests and holds vacuum (15") after the engine is shut down. I used the 'H' shaped gauge to check the MC push rod, the booster push rod is in the right hole. The one change I did make was move the Prop valve from the frame rail to under the MC. It is a 2 V for the F disc and D back as is the MC. I'm at my wits end. It does feel like the booster even though it checked out (and it is new).
