1972 442:

Did your new booster take care of the issue? I'm having a strange issue on my '64 Dynamic 88. The brake pedal was not returning and the fluid in my master cylinder was rusty, so I went ahead and installed a new master. However, when the engine is running the brake pedal drops to 1/2 its normal height and the engine nearly stalls when I hit the brakes (I have the car on jackstands). When I shut the car off, the brake pedal returns to its normal height after 10 seconds or so. I figure it is probably the booster. Any ideas?
