73 dart brake pedal interchange
I guess I could've read the title more closely, huh? :BangHead:
Anyhow, I can't help you with diagnosing your brake problem. My diagnostic procedure for power brakes goes like this:
Is there a problem?
Is there room on the scrap pile for a booster?
I've never bothered to attempt fixing a power booster beyond reconnecting the vacuum hose. Maybe someone with experience diagnosing and repairing power brakes can chime in on this.
