It appears the check valve is bad on the brake booster. I removed the check valve, started the car while plugging the check valve. When the car was turned off the vacuum did not stay. If I replace the check valve and cannot get one with multiple vacuum ports, I assume I can jut t in so everything is hooked to vacuum?
To verify brake booster/check valve operation...
1)With engine off pump brake pedal until it is hard.
2)While holding foot on brake pedal start the car, the pedal should drop.
3)Shut the car off and pump pedal, you should get 2-3 pumps of assisted braking before pedal gets hard.
